Sammo Hung will star in War Monkeys, a horror comedy from the indie arm of Dark Horse Films.

According to The Hollywood Reporter, Kevin Munroe (TMNT) is in negotiations to direct the film for Dark Horse Indie.

The horror comedy follows two janitors who, during a Christmas holiday, get trapped in an underground research facility after accidentally unleashing military-trained Rhesus monkeys. Hung is one of the janitors who battles the rabid simians.

Cleve Nettles wrote the script, based on a story by DHI producer Chris Patton. Robert Sanchez is also producing.

"Monkeys, guns, explosions. As a genre freak, I couldn't ask for anything more," said Munroe, who became obsessed with the project after initially agreeing to read a friend's work.

The monkeys will be a combination of real monkeys, animatronic puppets and CGI.

War Monkeys is eying an early 2009 start.
