Production Weekly's Twitter has an update on Tony Scott's next film Unstoppable. It seems that Rosario Dawson has joined this upcoming thriller. It is uncertain which role she will play, but Denzel Washington recently stepped down from the lead because of a money dispute only to rejoin the film a week later.

The story centers on a runaway train carrying a cargo of toxic chemicals. Denzel Washington and Chris Pine (playing an engineer and his conductor) are forced into a race against time, chasing the runaway train in a separate locomotive attempting to bring it under control before it derails on a curve and causes a toxic spill that will decimate a town.

Unstoppable will crash into theaters on November 10th, 2010.
