Denzel Washington has backed out of starring in 20th Century Fox's Unstoppable. According to Variety, the actor dropped out after waiting over three months for the studio to secure a budget and a fall start date. The actor is now looking for another project.

Tony Scott was set to direct the film, which would have found Washington playing a train engineer that jumps into a runaway locomotive full of toxic chemicals. With the help of a young conductor (Chris Pine), the two must stop the train before hitting a hairpin turn and decimating a small town. Washington was asked to shave $4 million off his $20 million asking price, but the actor declined the offer.

The studio is now shopping the project around to other actors. At this time, Tony Scott is still attached to direct.
