Denzel Washington is set to reteam with director Tony Scott for the fifth time in his career – he’s poised to sign on to new movie Unstoppable.

The pair has previously worked together on Crimson Tide, Man On Fire, Deja vu and the forthcoming The Taking of Pelham 1,2,3.

Unstoppable is loosely based on a real life event and is about an experienced engineer who jumps on a train to chase down a runaway locomotive transporting a cargo of toxic chemicals.
