Production notes

The series was first announced in February 2024 as The Donovans, a loosely based spinoff of the Showtime series Ray Donovan produced by MTV Entertainment Studios and 101 Studios, with Showtime/MTV executives Keith Cox and Nina L. Diaz and 101 Studios' David C. Glasser attached to the project. Ronan Bennett was hired to write the series and executive produce with Guy Ritchie, Ivan Atkinson, Glasser, Ron Burkle, Bob Yari and David Hutkin. In October 2024, the series was announced to have been reworked into a series with the working title The Associate, with Tom Hardy, Pierce Brosnan, and Helen Mirren in final negotiations to star. Production began in November 2024 with Hardy, Brosnan and Mirren in London and the working title was removed. Jez Butterworth, Tom Hardy, Dean Baker and Kris Thykier joined as executive producers. In February 2025, the final title of the series, MobLand, was revealed. On 23 June 2025, the series was renewed for a second season. In May 2026, a third season was confirmed to be in development. Hardy was initially reported to have departed the series after completing his work on the second season due to "friction" between him and showrunner Jez Butterworth. Later reports confirmed that Hardy "was not fired" from the series and that there were discussions about his return for a potential third season. The following month, Hardy was confirmed to return for the third season, alongside Brosnan and Mirren. On 3 September 2026, the series was renewed for a third season.

Tom Hardy, Pierce Brosnan and Helen Mirren signed on to star in the series in November 2024. Over the next month, Paddy Considine, Joanne Froggatt, Lara Pulver, Anson Boon, Mandeep Dhillon, Jasmine Jobson and Alex Fine were added to the cast. In February 2025, Geoff Bell, Daniel Betts, Lisa Dwan, and Emily Barber joined the cast. In March 2025, Janet McTeer joined the cast. In December 2025, Johnny Flynn and Ophelia Lovibond joined the cast as series regulars for the second season.

Production on the series took place between November 2024 and March 2025 in London. At least six of the episodes in the series were written during production, and filming wrapped only four days before the premiere. While filming, a bag of camera equipment was stolen from a set in East London. The thieves later returned and successfully stole more equipment, leading to the firing and replacement of the security team on set. During production, the set construction company, Helix 3D, went into bankruptcy, leaving several crew members with unpaid wages leading into the holiday season. Hardy initially offered to make up the difference before the production companies paid the workers instead.

MobLand's music is composed by Muse's Matt Bellamy and composer Ilan Eshkeri. The show's theme song is "Starburster" by Fontaines D.C. The first and second episodes feature songs by the Prodigy, "Firestarter" and "Breathe" respectively.
