Intruder is a 1989 American slasher film written and directed by Scott Spiegel, and co-written and produced by Lawrence Bender.

It received positive reviews from critics, with particular praise given for its unique setting of a grocery store for a slasher film.

Worried about her friend, her coworker, Linda, witnesses the debacle and presses her security button at her cash checkout.

The owners gather the night crew to announce that they are selling the store and that the staff will soon lose their jobs.

Craig tells Jennifer he saw Bill killing Linda, and that he climbed into the building through the bathroom window to save her.

He topples the phone booth over and traps her, but Craig appears and brutally damages him with a meat cleaver.

The film was partially based around Spiegel's experience working at the real Walnut Lake Market in Michigan.

The shelves were empty and bare and the crew had a company that specialized in damaged goods deliver over two tons of defective merchandise to stock the store.

The back cover of the DVD release makes it appear that Renée Estevez is the heroine, whereas in the film she is the first character to die.

The original VHS release from Paramount Home Video contained the R-rated version, which was missing five minutes of gore footage.

Adam Tyner of DVD Talk awarded the film four and a half out of five stars and wrote, "Intruder easily ranks up there as one of the best slashers I've ever seen".

While it includes all the genre tropes, it presents them in a way that feels fresher and more creative than many of the countless other maniac-on-the-loose films that the decade produced".
