Richard Saperstein has been elevated to prexy of production at Dimension Films and reupped for five years.

Saperstein, who had been running production as exec veep under co-chairman Bob Weinstein, drew a three-year extension and an option for another two years. He joined the company after it was reconstituted as part of the Weinstein Co.

Under Bob Weinstein, Saperstein has helped re-establish Dimension in the genre game since joining last June.

He oversaw production on “Scary Movie 4,” the upcoming Todd Phillips-directed “School for Scoundrels” and the Quentin Tarantino/Robert Rodriguez-directed “Grind House.”

Saperstein is spearheading development of the John Cusack-Samuel L. Jackson horror pic “1408,” based on the Stephen King novella; “Wichita,” with “Saw II” helmer Darren Lynn Bousman; “Welcome Back, Kotter” with Ice Cube; an adaptation of the King novel “Cell” with “Hostel” helmer Eli Roth; the Chuck Russell-directed “Piranha”; and “Quebec,” the directing debut of “The Pursuit of Happyness” scribe Steve Conrad.

“Richard is a leader and has been a tremendous asset to the Dimension team,” Weinstein said. “His new position and expanded responsibilities are representative of his hard work, success and dedication to the company.”

Since leaving his post as an ICM lit agent, Saperstein spent nine years at New Line and rose to senior exec veep under Michael De Luca, then ran production at Artisan Pictures for two years. Among the genre films he shepherded there was “Tonight, He Comes,” a film that moved to Sony and will be Will Smith’s next film. Saperstein remains an exec producer on the pic.
