**_Dr. Jekyll and Mr. Hyde meets Jack the Ripper with Anthony Perkins_** In London, 1888, Dr. Jekyll accidently discovers a form of smoking crack in the Victorian Era and thus his bestial alter ego, Mr. Hyde, goes on murderous excursions in the dead of night with oversexed prostitutes being his preferred prey.

"Edge of Sanity" often features scenes of sordid debauchery - Jekyll's amoral sexual attitudes stem from his childhood experiences, according to this film - which frequently run the risk of going too far in a film that quite frankly uses the extraordinarily imaginative and highly influencial central idea from Robert Louis Stevenson's novel as nothing more than a loosely presented excuse for all the sexual shenanigans that are going on. The results are of extremely limited consequence and it is obvious the film makers didn't really have much money to work with because Jekyll simply resembles Iggy Pop on this occasion instead of transforming into an entirely different person. The unfortunate reality is that this film unquestionably had the potential of being so much more than it actually is.
