Washington poised for fifth movie with Scott

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', 'Déjà vu' and the forthcoming 'The Taking of Pelham 1,2,3'.

Loosely based on a real-life event, 'Unstoppable' is about an engineer who jumps on a train to chase down a runaway locomotive transporting a cargo of toxic chemicals.
