There are two great things about this movie: James Spader’s performance and the unique, interesting, “Psycho”-like twist that occurs about half way through. The rest of the movie is mediocre at best, with a very routine serial killer plot. It would be best to see this movie without any knowledge of the twist, but the movie description already gives it away, so I will go ahead and say that Spader is fantastic at playing identical twins with slightly different personalities. This is the movie where Spader graduated to playing leading men. Before this, he played mostly bad guys and supporting characters. After this movie, he went on to star in “Sex, Lies and Videotape” and many other movies.
