After recently withdrawing from Tony Scott’s upcoming runaway-train flick Unstoppable over rumored salary concerns, Denzel Washington has signed back on for the project with his Taking of Pelham 1 2 3 director, according to his rep. The film is based on the true story of two men trying to stop a train filled with toxic materials from destroying a town. Star Trek‘s Chris Pine is slated to costar; shooting will start in September.
