Other mistake: When Graham is about to pull out the top video case shelf at the Leeds' home, you can see the movie "Jaws" on the second shelf. "Jaws" didn't come out on home video until 1991.
Other mistake: Looking at a close-up of Ralph Fiennes make-up for his cleft lip/palate, there is a scar from his left lip to his left nostril, but there is a gap in the middle, which should definitely not be there. Once an incision is made, that's it, there is no reason to stop in the middle. In other shots of his face there are no gaps.kh1616
Other mistake: When Graham and the police are headed to Dolarhyde's house (after visiting Chromalux), you can see a billboard as the police car squeals around a corner. It's an H&R Block billboard saying: "It's your refund. Get it faster." Didn't this slogan just come out a couple of years ago?
