In a story from Variety, Denzel Washington is in talks to star in the thriller Unstoppable.

The dramatic film will be directed by Tony Scott and released by 20th Century Fox.

The film is about a runaway train carrying a cargo of toxic chemicals. It pits an engineer (Washington) and his conductor in a race against time. They're chasing 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 will decimate a town.

Mark Bomback wrote the screenplay which is based on real events.

Unstoppable will be the fifth project for Washington and Tony Scott. Their other films include Crimson Tide, Deja Vu, Man on Fire, and they recently completed The Taking of Pelham 1 2 3.

Unstoppable is set to start shooting this fall.
