Rosario Dawson joins 'Unstoppable'

Rosario Dawson will star alongside Denzel Washington and Chris Pine in Fox’s runaway train drama "Unstoppable," directed by Tony Scott.

Dawson just wrapped Chris Columbus film "Percy Jackson" and is currently shooting "Zookeeper" opposite Kevin James for MGM and Sony. She was last seen in "Seven Pounds" with Will Smith.

Washington formally withdrew from "Unstoppable" in early July, then came to terms two weeks later to put the pic back on track for a fall start. He’s playing a veteran engineer who jumps into a locomotive with a young conductor (Pine) to stop an unmanned runaway train loaded with toxic cargo.

Julie Yorn is producing with Scott and Mimi Rogers, and Chris Ciaffa is exec producer. The script, penned by Mark Bomback, is loosely inspired by true events.
