School doesn’t just suck, it swallows in director Alex Craig Mann’s upcoming horror-comedy Detention of Dead. “Revenge” starlet Christa B. Allen plays the cheerleader in a group of high school delinquents serving detention during a sudden zombie apocalypse.

Detention of Dead costars Jacob Zachar (“Greek”), Alexa Nikolas (Red State), Jayson Blair (“Hard Times of RJ Berger”), Joseph Porter (Mega Piranha), Chon (Twilight Saga) and Max Adler (“Glee”).

Allen currently stars as rich and brainy party girl Charlotte Grayson, daughter of Victoria Grayson (Madeleine Stowe) on the hit ABC primetime soap “Revenge.” The pretty 20-year-old can also be seen opposite Charisma Carpenter in the psychological thriller Deadly Sibling Rivalry.
