Sure, it sounds like Resident Evil and every other menace-loose-in-a-scientific-facility film we've ever seen.
But this is monkeys.
Hong Kong superstar Sammo Hung (Enter the Fat Dragon) is in talks to star in War Monkeys, playing one of two janitors who is trapped in an underground (where else?) lab after accidentally setting loose super-soldier Rhesus monkeys.
The monkeys will be created using a mix of CG graphics, puppets, and real monkeys.
