Trivia: When Scream was reviewed by the MPAA, the executives utterly refused to release the film with the violent opening scene, considering it "too intense." As a result, Wes Craven had to lie to them, claiming that was the only take he was able to get and cutting the scene would downgrade the rest of the movie. After a few more cuts, the MPAA agreed to release the film under an R rating.
Trivia: After the release of this film, Caller ID sales shot up by over 300% for a period of time. The spike in sales was attributed to teens and young adults seeing this film and becoming frightened by the idea of receiving a phonecall and not knowing who was on the other side. This was a pretty big deal, too, as it was the mid-90's and Caller ID was not a standard feature on phones as it is now.
Trivia: One of the early signs that Stu is one of the killers is during the scene when Ghostface attacks Sidney in her house. When Ghostface chases Sidney up the stairs to her room, he says "Easy, easy!", which sounds like Stu's voice. Stu even says that same line to Tatum the next day when she hits him with the lollipop.
