Code Name: The Cleaner (2007)

When Jake (Cedric the Entertainer) awakes one morning in a strange hotel room, he finds himself in a bit of a predicament; there's a corpse in his bed and a briefcase full of cash. Not only that, but he cannot remember who he is or how he got there. He meets Gina (Lucy Liu), a waitress, who tells him he is a janitor at a video-game company and that she is a girlfriend. But Jake believes he is an undercover agent for the CIA, and he tries to figure out the truth.
