It's funny, and chock full of stars. It's a spoof of 50's B movies, so many of the actors have been around the block a few times. Don't worry, we're not talking Cocoon or Batteries Not Included, though.
It stars Jack Nicholson (dual roles!), Glenn Close, Jack Black, Natalie Portman, Paul Winfield, Ray J, Jim Brown, Pam Grier, Martin Short, Tom Jones, Annette Bening, Pierce Brosnan, Sarah Jessica Parker, Rip Torn, Danny DeVito, Michael J. Fox, Christina Applegate, Senator Fred Thomp-- um, I mean Joe Don Baker -- and an otherwise unknown named Janice Rivera as a showgirl, who manages to hold her own in all her scenes though she's always alongside Tom Jones, Jim Brown, and Annette Bening.
