Other: In the scene where Mark first meets the Countess and they are sitting at the bar, there is a shot of two girls in the background. In one shot the second girl walks away and then again in another shot the same girl walks away again.

Continuity: Near the end when the vampires are trying to get into the crypt and Jim Carrey has locked them out, we see two vampires trying to enter the room through one door and others going around to get in through the other entrance. When they get in, the vampires have reversed which entrance they were trying to use - the ones who stayed at the first door enter through the second door and vice versa.
