Sean Penn and Javier Bardem go head to head in first trailer for The Gunman: watch now

The first trailer for action thriller The Gunman has arrived online, starring Sean Penn as a professional killer who finds his past catching up with him in explosively OTT fashion.

Penn plays a former hitman for a shadowy organisation, who decides to turn away from his old life in order to start over with the woman he has fallen in love with.

However, things are never as easy as that in the professional killing game, and Penn’s old associate Javier Bardem isn’t about to let him swan serenely off into the sunset.
