A gaggle of actors have signed on for "National Lampoon Clubhouse Trick or Treat," says The Hollywood Reporter. And it's a pretty crazy cast of characters indeed.

The plot is described like so: "A 15-year-old boy is grounded on Halloween and stays home to baby-sit his brother and sister. They soon find that their old house is haunted, complete with a secret passage that leads them on a wild "Scooby Doo" and "Beetlejuice" - type adventure."

The cast will include Vanessa Angel ("Kingpin"), Robert Carradine ("Revenge of the Nerds"), Taylor Dooley ("Lava Girl" herself), Jake Thomas ("A.I. Artificial Intelligence"), Matthew Lawrence ("The Hot Chick"), and Nikki Griffin ("Wild Things: Diamonds in the Rough").

We'll bring you the direct-to-video release date as soon as it's made available.
