Whatever Billy Crudup did to Selena Gomez before this scene from her new musical drama "Rudderless," it was bad. Like, change your name and go into hiding levels of bad.

In this exclusive clip from the film, which hits theaters and Video On Demand on October 17, Gomez' character angrily approaches Crudup's Sam outside of a bar, where she scolds him for playing his dead son's (and her ex-boyfriend's) music.

"You don't remember me, do you?" she asks him, before the lightbulb goes off in his head.

"It's been better lately," she continues. "Things have died down. I even go out sometimes, like tonight. I go by 'Ann' now, it's my middle name."

"Ann" then proceeds to go off on Sam for performing the stolen music and, well, let's just say that this clip -- coupled with the standing ovation the film received at Sundance -- has us dying to see "Rudderless" ASAP.
