Casting Call: Rosario Dawson is 'Unstoppable,' Jaime King celebrates 'Mother's Day'

Now that its funding and lead actors are on board, "Unstoppable" is moving like, well, a runaway train.

Rosario Dawson will join Denzel Washington and Chris Pine on the disaster flick, according to Variety. "Unstoppable" was almost derailed earlier this year when 20th Century Fox balked at the movie's price, after which Washington bailed. Intensive negotiations, though, got the film and Washington's involvement back on track.

There's no word what sort of role Dawson will play. Washington and Pine signed on as engineers tasked with stopping a locomotive full of deadly chemicals.

-- "The Spirit's" Jaime King, meanwhile, is ready to suffer some Troma: King will star in a sort-of remake of the 1980 schlock-horror flick "Mother's Day."

The original followed a pair of murderous brothers out to impress their crazy mom by taking on campers in a remote forest; the new version will have the family returning to a previous home only to find a woman (King) and her estranged husband have moved in.

Deadly hijinx are sure to ensue.

Filming is set to begin in September for a possible release next Mother's Day.
