What’s not to love about the potential for this movie? Jason Statham plays an assassin who must rescue his mentor (Robert DeNiro) from a trio of assassins led by Clive Owen. There’s punching, guns, explosions and cocky one-liners from self-assured killers. It seems to be a good combination of things to make a fun action flick. The movie is supposed to be based on a true story from a book called The Feather Men by Sir Ranulph Fiennes, though there is some controversy surrounding the veracity of the original story.
