“Dr. Who” star Matt Smith is ready to cross the Atlantic to make his U.S. acting debut, taking the male lead in the Ryan Gosling-directed pic “How to Catch a Monster.”

Pic currently stars Christina Hendricks and Eva Mendes, and will mark Gosling’s directing debut.

Marc Platt and Adam Siegel will produce on behalf of Marc Platt Prods., along with Gosling via his Phantasma Films banner, and Michel Litvak and David Lancaster via the Bold Films banner.

Story is set against the surreal dreamscape of a vanishing city and centered on a single mother of two being swept into a macabre and dark fantasy underworld while her teenage son discovers a secret road leading to an underwater town. Production is set to start this spring.

The UTA and Troika-epped Smith has starred in a handful of BBC and British productions but never a stateside movie.

His third season of playing the Doctor recently wrapped and he also recently directed the short film “Cargese” for Sky Arts series Playhouse Presents.
