Chase scenes with nudity.
After seeing this film with its very lengthy (twenty minutes!) chase scene, I was wondering how many slasher or horror thriller films of this type tend to feature chase scenes with the woman being chased totally in the nude. Certainly, this is the longest nude scene I can ever recall seeing in a horror film.
Off the top of my head, there's this film, My Bloody Valentine (2009), the original Toolbox Murders, Kinky Killers, Emanuelle and the Last Cannibals, and I suppose Mute Witness (there's a scene where the woman being chased stops and bares all to try and get a neighbor's attention so he can call for help).
