The movie will premiere in cinemas on March 6 before becoming available on Netflix on March 20.
The minute-long trailer showcases explosions, gunfire, and a grey-haired Tommy Shelby in World War II-era Birmingham, stating, “I’m not that man anymore.”
New cast members Rebecca Ferguson and Barry Keoghan will join the series' universe, alongside returning actors including Tim Roth and Stephen Graham.
Series creator Steven Knight described the film as an “explosive chapter,” and the BBC also confirmed two additional TV seasons focusing on a younger generation of the Shelby family.
