Sean Penn is being hunted in a final television spot for The Gunman, Digital Spy reports.

The geo-political thriller casts Penn as expert assassin Jim Terrier, whose desire to live a quiet life leads his employers to turn against him.

Jim's former superior Felix (Javier Bardem) sets off a massive operation across Europe to take down the spurned assassin at any cost.

The Gunman also features action movie favourites Idris Elba and Ray Winstone in supporting roles.

Director Pierre Morel (From Paris with Love) has adapted the movie from Jean-Patrick Manchette's novel The Prone Gunman.

The Gunman opens on Friday (March 20) in the UK and the US.
