The Matador (2004)
Pierce Brosnan stars as a quirky assassin who strikes up an unlikely friendship with a businessman in a hotel bar in Mexico. They cross paths again several months later when the assassin seeks him out, needing help on one last job. Much lighter than most assassin movies, actually kind of touching in an odd sort of way. Very enjoyable.
