This is probably my all-time favourite action film (that doesn't involve superheroes, anyway). The use of narrative works really well here, and helps to play the story out in a really interesting way. Its best quality, however, is the incredibly witty script, which enables you to enjoy every moment of the film. As for the cast, RDJ and Kilmer make a brilliant leading duo and are the reason this film works so well, whilst Michelle Monaghan is pretty damn sexy.
