According to director Stephen Hopkins, they "got lots of tarantulas, hand-painted them green and red, and on the floor of the stage placed a little wall up in the shape of an arm and had trainers come in and around the tarantulas." The plan was to simply drop the wall and film the resulting scattering of the spiders, but after they got the shot they were left with a studio full of around 200 angry tarantulas. Hopkins figures, "We probably carried on shooting on another set, I'm sure. I don't think anyone ever found them again." As far as the director knows, those spiders roamed freely through the studio and escaped into the free world, or maybe it was just somebody else's job to ensure the tarantulas were all accounted for.

(at around 9 mins) During the graduation, while talking to Mark and Greta, Alice is seen holding the tickets to Europe before Dan has given them to her. They disappear for a bit and then Dan gives them to her a little later in the scene.

In the end credits, Lisa Wilcox's (Alice) name is omitted, possibly due an oversight with the end credits being listed alphabetically and the fact that her last name would have put her last on the list.

Although the UK cinema and video versions were fully uncut the DVD release features the R-rated U.S print which is missing around 15 secs of gore. The fusion scene between Dan and the bike is shortened and the scene where Freddy forces Greta's innards into her mouth is cut (his voice can be heard saying "You are what you eat").
