Watch a Trailer in Which Sean Penn Pretty Much Plays Liam Neeson

The trailer for The Gunman, the big-screen adaptation of the bestselling novel The Prone Gunman by Jean-Patrick Manchette, has arrived. Sean Penn plays Jim, an assassin who decides he wants out of the business, but his organization isn't letting him go just like that. His big, bad boss (Javier Bardem) is pissed, and war between the two ensues. Things get real when Jim's girlfriend (Jasmine Trinca) is kidnapped and he has to go into full-on Liam Neeson mode. The film's director, Pierre Morel, also directed Taken, so the parallel isn't too far-fetched. The movie opens on March 20; get a peek with the trailer below, and then check out all the movie trailers for films opening in 2015!
