Mr. Right (2015)

Storyline:

Hyperactive at the best of times, Martha (Anna Kendrick; Pitch Perfect) has gone full-on manic since her latest breakup. She babbles, parties like a monster, cooks everything in sight - and is looking to do something terrible when she meets Francis (Sam Rockwell; The Way Way Back). To anyone else, Francis's approach would come across as creepy, but Martha can't help but be intrigued. They seem a perfect match: she's bananas, he's bananas... except he's a deadly sort of bananas. He's a professional assassin. Francis is a hitman with a cause: he unexpectedly kills the people ordering the hits. Just as Martha begins to realize her new beau wasn't joking when he said he had to step out for a moment to shoot someone, things start heating up for Francis. His services are solicited by a dubious client who's being sought by an equally dubious FBI agent (Tim Roth; Pulp Fiction, Reservoir Dogs). As the bodies pile up, Martha needs to decide whether to flee or join in the mayhem.
