Brittany Murphy is on the verge of a comeback - - potentially, anyway.

The young actress, who the hit the big time in films like “Riding in Cars with Boys” and “8 Mile” and somehow ended up doing direct-to-dvd drivel like “The Ramen Girl” and “Neverwas”, has snagged a plum role in Sylvester Stallone’s all-star protein-shake commercial “The Expendables”.

Murphy will play Mickey Rourke's girlfriend, a singer. The part calls for her to perform a musical number.

Based on the script pages I’ve read, I believe Murphy’s character only appears briefly – in a nightclub scene in which ‘The Expendables’ approach Rourke’s arms-dealer about some assistance on the job. From memory, the part Murphy would be playing is similar to Minnie Driver’s in Martin Campbell’s James Bond flick “Goldeneye”.

Murphy and Rourke previously worked together on "Sin City".

Meantime, The Hollywood Reporter says David Zayas (Angel on TVs “Dexter”) is playing the dictator the expendables have been hired to overthrow.

Principal photography is currently taking place in Brazil, and will move to Louisiana for the second half of filming. The film hits theatres this time next year.
