We already know that A$AP Rocky is a great rapper -- and a great model -- so now it's time for him to try something new: acting.

The Harlem rapper is set to make his big screen debut in a new film called "Dope," which will premiere at the Sundance Music Festival.

The storyline will follow a young hip-hop fan who grows up in the rough neighborhood of Inglewood, Calif., and it will include cameos from other artists, including Tyga, Casey Veggies, Vince Staples and Diddy's son Quincy Brown, in addition to the main cast.

Rocky landed a supporting role as a cast member called "Dom," after he requested his own audition while helping his model ex-girlfriend, Chanel Iman, to prepare for her own lines.

Oh, and Pharrell helped director Rick Famuyiwa score the film, which means that the soundtrack will probably be great.

“It was exhilarating to sit there in the studio with Pharrell as he composed this music,” Famuyiwa told EW. “I’d tell him about Malcolm and then he’d disappear to his magic lair, or wherever he goes, and then he’d have a song about it and it’d be amazing. I think he was key in helping me figure out who these kids are in this world.”
