Now known as Escape 2000, this is one of those brilliant Australian movies featured in the excellent documentary Not Quite Hollywood. Featuring a cast of both Australians and Americans, it is set in a futuristic concentration camp where you expect Pam Grier or Phyllis Davis to be taking a shower. Instead, you've got Olivia Hussey and Lynda Stoner (who spends a lot of time running around bra-less in her jumpsuit). A ridiculous amount of fun. The sad thing is that I have not ever heard of Lynda Stoner having done a nude scene in her career, so this may be the best there is.
