Fox's thriller UNSTOPPABLE has a director: Tony Scott, who will helm the project as his next film, according to VARIETY.

The hire puts the production on the fast track, with Scott to work with screenwriter Mark Bomback on prep. Julie Yorn is producing with Scott on the film, set to begin filming later this year.

UNSTOPPABLE involves a runaway train carrying a cargo of toxic chemicals that an engineer and his conductor must stop from crashing.
