EXCLUSIVE: Looks like the sides have been chosen for the shoot-out film The Gunman, which Taken helmer Pierre Morel will direct for Silver Pictures and Studio Canal. Ray Winstone has just joined the film. He’ll play the mentor of the hitman played by Sean Penn, who is betrayed and then hunted by the organization he worked for. On the opposite side of this twosome are Javier Bardem and Idris Elba, and they run all over Europe in a fatal game of cat and mouse. Jasmine Trinca (Miele) is the female lead. Winstone’s tough guy cred includes The Departed, Sexy Beast, 44 Inch Chest and the upcoming Darren Aronofsky-directed Noah, where he goes mano a mano against Russell Crowe in that Biblical epic. I hope this movie is as good as it sounds here, because I’d follow these four actors anywhere. The Gunman is based on the Jean-Patrick Manchette novel Prone Gunman, scripted by Pete Travis. Joel Silver and Andrew Rona are producing. Resolution reps Winstone.
