Plus, Amanda Peet joins "Gulliver's Travels"

Don Johnson wants everybody to get naked, and Amanda Peet is ready to travel.

Johnson has signed on to play a porn director in Adam Sandler's "Born to be a Star," according to The Hollywood Reporter.

The story follows a small-town boy (Nick Swardson) who learns his parents were once famous adult-film stars. Johnson's director will give Swardson's character a chance to follow in their bare footsteps.

Peet, meanwhile, will co-star in the Jack Black-headed update of "Gulliver's Travels." She'll play Black's editor, who sends him on an assignment that lands him captured by the tiny residents of Lilliput.

Filming has already begun on both movies.
