Plot hole: The whole film is basically told as a flashback from Rand Peltzer's point of view. Now he might be able to talk about things that Billy, his mom, or Kate might have told him, but he wouldn't have known about all the other the gremlins did to the rest of the town like killing Mrs. Deagle, the cops, or the gremlin in the mailbox.
Gremlins (1984)
1 plot hole - chronological order
Directed by: Joe Dante
Starring: Phoebe Cates, Zach Galligan, Hoyt Axton, John Louie
Revealing mistake: When the professor is trying to find the gremlin, he is in the room with the movie playing. The projector that is playing the movie is actually moving backwards. (00:44:35 - 00:47:35)
Randall Peltzer: Well, that's the story. So if your air conditioner goes on the fritz. Or your washing machine blows up. Or your video recorder conks out; before you call the repairman, turn on all the lights, check all the closets and cupboards, look under all the beds. Cause you never can tell. There just might be a gremlin in your house.
Trivia: When Billy's mom takes the picture of Gizmo at the beginning, Gizmo becomes frightened and runs over to Mr. Peltzer. When the scene is slowed, you can see the puppeteer's hand underneath while operating the Gizmo doll. Not a mistake as needs slo-mo, but worth a look. (00:19:10)
Question: I have the original VHS version and I've noticed that some cuss words have dubbed over on the DVD. Yet The original VHS is still rated PG any reason why, other than the fact to make it more of a family film.
Answer: The original film was released before the PG-13 rating existed (it was one of the films responsible for its creation). Producers decided to remove some of the language and violence for the DVD release to avoid complaints about the PG rating.
