Joel Silver’s Dark Castle has set “I Saw What You Did,” a remake of the 1965 William Castle-directed “I Saw What You Did and I Know Who You Are!”

Patrick Lussier and Todd Farmer will write and Lussier will direct.

The original Castle pic, 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.

Pic will be produced by Silver, Andrew Rona and Steve Richards. Dark Castle will finance and distribute through Warner Bros.

Lussier has a long relationship with Dark Castle prexy Rona, which goes back to his editing the first “Scream,” when Rona was co-president of Dimension.

Dark Castle’s first film was a remake of William Castle’s 1959 pic “House on Haunted Hill.”

Lussier and Farmer teamed on “My Bloody Valentine 3D,” which Lussier directed and Farmer co-wrote.

Paradigm reps the duo.
