Leonardo DiCaprio & Michelle Williams Flash Their Shutter Smiles

Leonardo DiCaprio and costar Michelle Williams shoot scenes for their new movie, Shutter Island, in Boston, Mass., on Sunday morning.

Their costars Mark Ruffalo (pictured below), Ben Kingsley and director Martin Scorsese were also spotted on set.

Shutter Island takes place in 1954 and is about U.S. Marshal Teddy Daniels (DiCaprio), who is investigating the disappearance of a murderess who escaped from a hospital for the criminally insane and is presumed to be hiding on the remote Shutter Island. Emily Mortimer and Patricia Clarkson also costar.

Michelle can’t be pregnant, right? Right?
