Matchstick Men
Roy (Nicolas Cage) is a con man with an issue. He is an obsessive compulsive (among other things). He has to open and close doors three times (each – although there are a few times that he forgets, which indicates that perhaps it’s all in his head).
Luckily, he has a caring partner in Frank (Sam Rockwell), who helps him remember to take his medicine when he needs to do so, and manages to set up plenty of short cons, where Roy can just walk in and help clean up the mess so that they can rake in some easy, if small, money. Frank just wants to get Roy to make a big hit.
