When Kat is dancing on stage, just before the solider rips her throat out she is wearing a skimpy silver bikini. After her throat is ripped out and she is carried to her dressing room, she gets up and walks out. Miraculously she is wearing a silver and black Basque and thong, without having any time to get changed.
What are the differences between the R-Rated version and the Unrated Version?
This splattery comedy with pornstar Jenna Jameson and horror icon Robert Englund had a limited theatrical release in the US. For this, some cuts had to be made in order to secure the R-rating. But not only were some gory scenes cut to lower down their effect but also some scenes featuring nudity were replaced by more harmless shots. This is typical MPAA censorship and became almost normal for today's unrated releases. A detailed comparison between the theatrical cut and the unrated version can be found here.
