Brad Pitt is reportedly set to star in Bullet Train, a new assassin thriller from Deadpool 2 and Atomic Blonde director David Leitch - his former stunt double.

The Hollywood Reporter says the film is based on the Japanese book Maria Beetle by Kotaro Isaka and tells the story of a group of assassins with conflicting motives on a Tokyo train. Sources have said that Pitt will play an American hitman known as Ladybug.

"The project has been tonally described as Speed, the Keanu Reeves action film set on a bus, meets Non-Stop, the 2014 Liam Neeson thriller set on a plane," says the Hollywood Reporter.

Director David Leitch is Brad Pitt's former stunt double

The plan is for Bullet Train to begin filming in the Autumn with the contained nature of the story making it easier to film under Covid-19 restrictions than a project with multiple locations.

Pitt previously made a cameo in director Leitch's Deadpool 2. Before going behind the lens, Leitch was Pitt's stunt double on a number of films, including Mr and Mrs Smith, Troy and Ocean's Eleven. His most recent film as director was the Fast & Furious spin-off Hobbs & Shaw
