The props department snuck many Doctor Who references into the Peter Vincent apartment set (for example, Gallifreyen writing - the Doctor's native language - on certain items), as a homage to actor David Tennant, who was playing Peter Vincent and previously played The Doctor. The majority of these references are not visible to the audience.
Counting flashback footage, Chris Sarandon is the only actor to appear in all three Fright Night films. In the original Fright Night (1985), he plays the role of Jerry. In the 2011 remake, he has a cameo as the man who hits the Brewsters' car and is subsequently bitten by Jerry.
Steven Spielberg made two major contributions to the film. The first one was an insert shot of the crucifix falling in the pool directly in front of the camera (after Jerry attacks Ed Lee). The other one was Jerry's fourth stage makeup - when previewed, he said that it was not scary enough and insisted that the original concept of a shark-like jaw be put back.
The club scene originally included a fight between feuding frat boys that was broken up by Jerry with the use of his hypnosis powers. Although the scene was cut, the frat boys can still be seen around the DJ booth when the t-shirts are thrown into the crowd.
