Production notes

Immediately after finishing Spider-Man (2002), director Sam Raimi signed on to direct a sequel. In April 2002, Sony hired Smallville (2001–2011) alumni, Alfred Gough and Miles Millar to write a script for the film, as Raimi, producer Laura Ziskin and star Tobey Maguire enjoyed Smallville. On May 8, 2002, following Spider-Man's record-breaking $115 million opening weekend, Sony Pictures announced a sequel for 2004. Entitled The Amazing Spider-Man, after the character's main comic book title, the film was given a budget of $200 million and aimed for a release date of May 7, 2004. The following month, David Koepp was added to co-write with Gough and Millar. Koepp originally wanted to do the Gwen Stacy and Harry Osborn story and have Gwen to be killed in the middle of the second movie. The film's title The Amazing Spider-Man was a placeholder title, and other titles were proposed, such as Spider-Man 2 Lives, Spider-Man Unmasked, and Spider-Man: No More. In September 2002, Michael Chabon was hired to rewrite. His draft had a younger Doc Ock, who becomes infatuated with Mary Jane Watson. His mechanical limbs use endorphins to counteract the pain of being attached to his body, which he enjoys. When he injures two muggers on a date, this horrifies Mary Jane, and in the resulting battle with Peter Parker / Spider-Man, his tentacles are fused, and the fusion begins to kill him. In the script, Octavius is the creator of the genetically altered spider from the first film, and gives Peter an antidote to remove his powers: this means when Octavius is dying with his tentacles, he wants to extract Spider-Man's spine to save himself. This leads to an alliance with Harry (a detail which made it into the finished film). Beforehand, Harry and the Daily Bugle put a $10 million price on Spider-Man's head, causing the city's citizens to turn against him. Chabon turned in his script to Sony but no one agreed with his take. Raimi sifted through the previous drafts by Gough, Millar, Koepp and Chabon, picking what he liked with screenwriter Alvin Sargent. He felt that thematically the film had to explore Peter's conflict with his personal wants against his responsibility, exploring the positive and negatives of his chosen path, and how he ultimately decides that he can be happy as a heroic figure. Raimi took inspiration from Superman II (1980) for the story of Peter giving up his responsibilities. Although the story takes some partial influence from Doc Ock's debut in 1963 and the 1966 storyline If This Be My Destiny...!, the story was mostly inspired by the 1967 storyline Spider-Man No More!, specifically The Amazing Spider-Man #50. It was decided that Doctor Octopus would be kept as the villain, as he was both a visually interesting villain who was a physical match for Spider-Man, and a sympathetic figure with humanity, accompanied by the fact that the character had been repeatedly considered as a villain for the first film over the course of its 15-year development. Raimi changed much of the character's backstory, however, adding the idea of Octavius being a hero of Peter, and how their conflict was about trying to rescue him from his demons rather than kill him. Raimi confirmed Doctor Octopus as the film's antagonist in November 2002.

When Tobey Maguire signed on to portray Spider-Man in 2000, he was given a three-film contract. After filming Seabiscuit (2003) in late 2002, a pre-existing back condition that Maguire suffered from was bothering him. Raimi heard that Maguire could be paralyzed if there was an injury in his back. Jake Gyllenhaal was cast to replace Maguire; the two actors so resemble each other that "a source close to Maguire" reportedly said that, had Gyllenhaal taken over the role, "A year from now? The public wouldn't know the difference". Maguire's girlfriend's father Ronald Meyer—head of Universal Studios—helped Maguire regain the role, with a salary of $17 million. Maguire underwent tests to make sure if his back was fit for filming. Gyllenhaal would eventually play Quentin Beck / Mysterio in the Marvel Cinematic Universe (MCU) film Spider-Man: Far From Home (2019) and said in an interview around that time that he was one of several actors considered to replace Maguire. Raimi stated that before filming he was concerned that Maguire and Dunst weren't going to have the same chemistry, as they had since broken up. Elizabeth Banks was announced to reprise her role as Betty Brant in January 2003. Several actors were considered for the part of Doctor Octopus, including Ed Harris, Chris Cooper (who went on to play as Norman Osborn in the 2014 film The Amazing Spider-Man 2), and Christopher Walken; Alfred Molina was cast as Otto Octavius in February 2003 and underwent physical training for the role. Molina initially signed a three-picture deal where it said that they have the right to renew the option. The reaction to his casting was mixed. Raimi had been impressed by his performance in Frida (2002) and also felt that his large physical size was true to the comic book character. Molina only briefly discussed the role and was not aware that he was a strong contender. He was a big fan of Marvel Comics and was excited to get the part. Although he was not familiar with Doc Ock, Molina found one element of the comics that he wanted to maintain, the character's cruel, sardonic sense of humor. Molina signed a three-film option with a contract that stated the producers could choose to renew it if they decided to bring him back, with producer Avi Arad assuring him that nobody really dies in the Marvel Universe when Molina told him and his fellow producers he assumed the option was null and void upon filming his character's death scene.

Spider-Man 2 was shot on over one hundred sets and locations, beginning with a pre-shoot on the Loop in Chicago during two days in November 2002. The crew acquired a train of 2200 series cars, placing sixteen cameras for background shots of Spider-Man and Doc Ock's train fight. Members of the film's production team acknowledged that the surroundings of where the Chicago subway car was filmed do not correspond to the kinds of routes that present day New York City subway cars travel. Filming was originally slated to start in January 2003, but was pushed back to April so that Maguire could finish Seabiscuit. Principal photography began on April 12, 2003, in New York City and Chicago. The crew moved on May 13 to Los Angeles, shooting on sets created by production designer Neil Spisak. After the scare surrounding his back pains, Maguire relished performing many of his stunts, even creating a joke of it with Raimi, creating the line "My back, my back" as Spider-Man tries to regain his powers. Raimi said that while filming the scene he yelled at Maguire to get to the edge of the building, but Maguire refused to do it. Even Rosemary Harris took a turn, putting her stunt double out of work. In contrast, Molina joked that the stunt team would "trick" him into performing a stunt time and again. J. K. Simmons said that while filming the scene where Spider-Man gets his suit back from the Daily Bugle, when Simmons said "he's a thief," his fake teeth popped out of his mouth. Filming was put on hiatus for eight weeks in order to build Doc Ock's pier lair. It had been Spisak's idea to use a collapsed pier as Ock's lair, reflecting an exploded version of the previous lab and representing how Octavius's life had collapsed and grown more monstrous, evoking the films of Fritz Lang and the movie The Cabinet of Dr. Caligari (1920). Filming then resumed on that set, having taken fifteen weeks to build, occupying Sony's Stage 30. It was 60 feet (18 m) by 120 feet (37 m) long, and 40 feet (12 m) high, and a quarter-scale miniature was also built for the finale as it collapses. Reshoots for the film wrapped in February 2004. A camera system called the Spydercam was used to allow filmmakers to express more of Spider-Man's world view, at times dropping fifty stories and with shot lengths of just over 2,400 feet (730 m) in New York or 3,200 feet (980 m) in Los Angeles. For some shots, the camera would shoot at six frames per second for a faster playback, increasing the sense of speed. Shots using the Spydercam were pre-planned in digital versions of cities, and the camera's movement was controlled with motion control, making it highly cost-effective. The camera system was only used in the previous film for the final shot.

Although roughly the same as before, costume designer James Acheson made numerous subtle changes to Spider-Man's costume. Its colors were made richer and bolder, its spider emblem was given more elegant lines and enlarged, its eye-lenses were somewhat smaller, and its muscle suit underneath was made into pieces, to give a better sense of movement. The helmet Maguire wore under his mask was also improved, with better movement for the false jaw and magnetic eyepieces, which were easier to remove. To create Doc Ock's mechanical tentacles, Steve Johnson's Edge FX was hired to create a corset, a metal and rubber girdle, a rubber spine and four foam rubber tentacles which were 8 feet (2.4 m) long and altogether weighed 100 pounds (45 kg). The claws of each tentacle, which were called "death flowers", were controlled by one puppeteer sitting on a chair. Each tentacle was controlled by four people, who rehearsed every scene with Molina so that they could give a natural sense of movement as if the tentacles were moving due to Octavius's muscle movement. On set, Molina referred to his tentacles as "Larry", "Harry", "Moe" and "Flo", with "Flo" being the top-right tentacle as it was operated by a female grip, and performed delicate operations like removing his glasses and lighting his cigar. Edge FX was only hired to do scenes where Octavius carries his tentacles. CGI was used for when the tentacles carry Octavius: a 20 ft (6.1 m) high rig held Molina to glide through his surroundings, with CGI tentacles added in post-production. The CGI versions were scanned straight from the real ones to allow them to appear more realistic. However, using the real versions was always preferred to save money, and each scene was always filmed first with Edge FX's creations to see if CGI was truly necessary. In some shots where CGI is used, Molina is replaced by a virtual actor possessing the CGI tentacles. Through the use of motion-capture and cyber-scanning, visual effects supervisor Scott Stokdyk and CGI character animation supervisor Anthony LaMolinara were able to create more detailed virtual actors to replace Maguire and Molina in some shots, as well as make them display natural human motion. Completing the illusion, the sound designers chose not to use servo sound effects, feeling it would rob the tentacles of the sense that they were part of Octavius's body, and instead used motorcycle chains and piano wires. As with the previous film, John Dykstra served as visual effects designer. Dykstra and his crew sought to make the weakest shot of the second movie look as good as the best shot of the first movie. Dykstra not only created the physical appearance of Octavius's tentacles, but also that of the nuclear reaction that Octavius attempts to carry out in the film. The reaction resembles the sun, complete with solar flares, and poses a threat to its immediate environment through its strong gravitational pull, which can draw surrounding objects directly into it and disintegrate them. As mentioned previously, the film's increased budget allowed the reaction to have a significant amount of artistry and reality.

Spider-Man 2 opened in the United States on June 30, 2004, and grossed $40.4 million in its first day; this broke its predecessor's opening day record of $39.4 million until it was surpassed a year later by Star Wars: Episode III – Revenge of the Sith ($50.0 million). Playing at 4,152 theaters upon opening, it had the second-highest number of screenings of any film, behind Shrek 2. The film also broke The Lord of the Rings: The Return of the King's record ($34.5 million) for the highest-grossing Wednesday of all time.

Additionally, it had the highest Monday gross of any film, generating a total of $27.6 million. The film would hold this record for a decade until it was eclipsed by Star Wars: The Force Awakens ($40.1 million) in 2015. Spider-Man 2 became the quickest film to hit the $200 million mark, taking eight days to do so. This record would be tied with Revenge of the Sith and Pirates of the Caribbean: Dead Man's Chest. All three films were surpassed by The Dark Knight in 2008. Internationally, Spider-Man 2 opened in 28 territories and grossed $43 million in its first week.

Spider-Man 2 received critical acclaim upon release. On the review aggregator website Rotten Tomatoes, Spider-Man 2 holds an approval rating of 93% based on 276 reviews, with an average score of 8.3/10. The website's critical consensus reads, "Boasting an entertaining villain and deeper emotional focus, Spider-Man 2 is a nimble sequel that improves upon the original." Metacritic, which uses a weighted average, gives the film a score of 83 out of 100 based on 41 reviews, indicating "universal acclaim". Audiences polled by CinemaScore gave the film an average grade of "A−" on an A+ to F scale, the same grade earned by the previous film. Chicago Tribune gave the film three and a half stars out of four, and Mark Caro stated that Alfred Molina was a "pleasingly complex" villain, and the film as a whole "improves upon its predecessor in almost every way." William Arnold, of the Seattle Post-Intelligencer gave it a positive review, saying, "Forget Raising Helen and The Notebook, this is the movie summer's most touching young romance." Kenneth Turan, of the Los Angeles Times, gave the film four stars out of five and concurred with Caro when he stated, "Doc Ock grabs this film with his quartet of sinisterly serpentine mechanical arms and refuses to let go." Roger Ebert gave Spider-Man 2 four stars out of four, calling it "the best superhero movie since the modern genre was launched with Superman (1978)", and praising the film for "effortlessly [combining] special effects and a human story, keeping its parallel plots alive and moving." He later called it the fourth best film of 2004. Joe Baltake of The Sacramento Bee gave the film his highest possible score, calling it "the closest thing to an art-house action film since Tim Burton's original Batman in 1989." IGN's Richard George felt "Sam Raimi and his writing team delivered an iconic, compelling version of Spider-Man's classic foe... We almost wish there was a way to retroactively add some of these elements to the original character." In 2016, James Charisma of Playboy ranked the film #9 on a list of "15 Sequels That Are Way Better Than The Originals". Conversely, J. Hoberman, of The Village Voice, thought the first half of the film was "talky bordering on tiresome", with the film often stopping to showcase Raimi's idea of humor. Peter Bradshaw of The Guardian gave it 3 out of 5 stars, writing, "In between the combat scenes it gets a little dull and I've never found the seething resentment of Peter's friend Harry Osborn ... particularly interesting. Doc Ock's much better value." The cast's performances were widely acclaimed. Ebert, who had panned the first film yet praised Maguire's performance, reciprocated his praise, writing, "if Maguire hadn't returned (along with Spidey's throwaway line about his aching back), we would never have known how good he could be in this role." He also wrote that Dunst "[brought] depth and heart to a girlfriend role that in lesser movies would be conventional. When she kisses her astronaut boyfriend upside-down, it's one of those perfect moments that rewards fans of the whole saga; we don't need to be told she's remembering her only kiss from Spider-Man." Concerning Molina's performance, ABC News wrote, "Molina is one of the summer's greatest scene-stealers — and now, instantly recognizable. How long can you play an eight-limbed monster and a Broadway fiddler before audiences get distracted?... The answer: So far, so good. Playing to packed houses, Molina can apparently fiddle on the finest roofs on Broadway without the extra metal limbs getting in the way. They may even help." in a 5-star review, Josh Wilding of ComicBookMovie.com added, "[Molina] is excellent, and Doc Ock is an unhinged, terrific bad guy who serves as an undeniably worthy follow-up to Willem Dafoe's memorable Green Goblin," in addition to praising Danny Elfman's score and the visual effects.

In 2022, Rolling Stone ranked Spider-Man 2 as the second-best superhero film of all time, behind Black Panther (2018). Rotten Tomatoes ranked it number 15 on a list of the top 100 superhero films, and ranked it 31st on its list of Essential 2000s Movies. The film was placed 411th on Empire magazine's top 500 movies list, describing the film as "Bigger and better than its predecessor, with a superior villain in Alfred Molina's Doc Ock, and a more confident Raimi sneaking in some of his own trademarks." In 2018, Film School Rejects called it "the best summer movie ever" and said that its "emotional and calculated story stands above modern summer flicks" like those of The Avengers and The Dark Knight. Writing for The Independent in 2019, Al Horner believed the film to be "the definitive superhero movie" that "laid the blueprint for the entire modern superhero genre". Digital Trends' David Caballero named Spider-Man 2 the best superhero movie of all time for its 20th anniversary in 2024. In 2026, IndieWire ranked it 21st on list of 100 Best Movie Sequels.
