Artisan Entertainment is close to finalizing a deal to purchase the spec script “Allison” written by Brian King. Sarah Michelle Gellar is in advanced negotiations to star.AMG sent the script out wide Thursday but Artisan preemptively took it off the market. The script is said to be a high-tension thriller in the vein of Alfred Hitchcock’s “Rebecca.” Story revolves around a young college woman struggling to pay her debt who falls prey to a set of terrifying circumstances. AMG’s Cathy Schulman and JoAnne Colonna brought the project to Artisan. AMG, along with Greg Silverman, will produce and Artisan will distribute. King and Gellar are repped by ICM.
