Directed by Ang Lee (Life of Pi) and co-written by David Benioff (Game of Thrones), the film features Smith as Henry Brogan, an older, experienced assassin. However, the contract killer suddenly finds himself in the crosshairs of a younger hitman who can seemingly predict his every move, and Brogan quickly discovers it's a younger incarnation of himself, trained by a mysterious character played by Clive Owen.
