Joel Silver's Dark Castle is developing the horror movie I Saw What You Did, a remake of the 1965 William Castle-directed I Saw What You Did and I Know Who You Are!, Variety reported. Patrick Lussier and Todd Farmer will write, and Lussier will direct.

The original Castle movie, which starred Joan Crawford, was based on the Ursula Curtis novel Out of the Dark and revolved around two girls who innocently pass the time making prank phone calls to unsuspecting people until they call the wrong guy.

The movie will be produced by Silver, Andrew Rona and Steve Richards. Dark Castle will finance and distribute through Warner Brothers.
