Mickey Rooney, Dick Van Dyke and Bill Cobbs have signed on to play villains opposite Ben Stiller in action-comedy Night at the Museum.

The trio will play fellow security guards of Stiller's character, a bungling nightwatchman who inadvertently sets off a curse which bring the insects and animals on display at the Museum of Natural History to life.

Directed by Shawn Levy, Night at the Museum is slated for a December 22 release.
