Rosario Dawson has signed on to star alongside Denzel Washington and Chris Pine in Tony Scott’s action drama Unstoppable.  No mention of what character Dawson would play, but one would assume that she’s the romantic interest or wife of either Washington or Pine.

Washington briefly withdrew from the project in early July after Fox asked him to shave a few million off his asking price. Variety reports that Washington and Fox came to an agreement two weeks later, and the project is now on track to begin filming this fall.

Screenwriter Mark Bomback (Live Free or Die Hard, Deception, Race to Witch Mountain)’s script is loosely inspired by true events, and tells the story of  an experienced engineer (Washington) who finds himself teaming up with a young conductor (Pine) in a race against time, with a runaway train carrying a cargo of toxic chemicals. The duo chase the runaway train in a separate locomotive and need to bring it under control before it derails on a curve and causes a toxic spill that could decimate a town.

The project has gone under two previous titles: Runaway Train and 8888, named after the CSX locomotive model number, often referred to as “Crazy Eights” because of two separate incidents in Ohio, one a derailment, the other a runaway train the film is loosely based on.

A runaway freight train traveled 70 miles with no one at the controls for nearly two hours before rail workers were able to slow it down by latching a second engine to the end of the train and applying the brakes. While two of the train’s tank cars contained thousands of gallons of the hazardous material molten phenol acid, the runaway train itself was considered more of a threat than the chemicals on board.
