Character mistake: When Frenchie is the only person remaining in the soda shop a guardian comes on and starts singing a song. While he is singing the song (toward the end of his singing) all the girls scatteringly head back toward the stairs. While they are walking up, one of the girls trips over her high heels. It is clearly shown, she's toward the front going around the back of the seat Frenchie is sitting in, around the round thing.
Grease (1978)
1 character mistake
Directed by: Randal Kleiser
Starring: John Travolta, Stockard Channing, Olivia Newton-John, Jeff Conaway, Kelly Ward, Michael Tucci
Factual error: The movie and events take place in 1958. However, two Fender amplifiers that are used by the band, "Johnny Casino and The Gamblers" are "Silverface" models that were only manufactured between 1967 and 1981.
Danny: Uh, I'm not very hungry; just gimme a double Polar Burger wit' everything and a cherry soda wit' chocolate ice cream.
Trivia: Olivia Newton-John had to be sewn into her trousers at the end of the film as the zipper broke. They were put on in the morning and she was not allowed to take them off or go to the restroom while they were on, as the crew would have to waste time sewing them back on.
Question: I can't understand why Sonny hauled Sandy off the dance floor during the dance finale. Sure Sonny was a bit of a jerk, but he idolized Danny and would never disrespect him. Also there was nothing to suggest that he and Cha-Cha were friends. I never truly understood.
Answer: He's fall-down drunk, that's why. He's drinking during the entire dance.
Answer: Because in real life Olivia was late for work, as a result Annette had to take Olivia's place because she was her understudy.
Answer: It's a terrible moment in the story because it exposes Danny as being thoughtless. After already burning Sandy once (at the pep rally) you'd think he'd be mindful of not doing it again. This time, though, he humiliates her in front of the entire school, as well as on television. Unsure how Sandy's sitting with him in the next scene at the drive-in only slightly miffed. Imagine how this plays as a story to their children: "Hey, kids, did I ever tell you about how your dad embarrassed me in front of everybody?" I guess it's meant to be partly motivation for Sandy to change her image and outlook in order to keep Danny, but it's a terrible message (even back then). She's nothing but thoughtful and considerate, and Danny repeatedly treats her badly, but she decides she needs to reinvent herself. (Danny's makeover doesn't count given it lasts about three minutes.) It would've been better had Danny and Sandy came second because of Sandy's dancing, and that could've played on her mind.
Answer: He is so upset about Marty liking Ed Byrnes, he just drinks all night.
Answer: I think it was because Sonny was drunk and wanted Sandy to talk to Marty for him since she dumped him for Vince Fontaine at the beginning of the dance.
Answer: Well my theory is maybe since Sonny wants a girl, Cha-Cha promised him a date with a girl if he agreed to her plan.

Answer: Watched that scene again now and I just think it was poor writing (in what's still a classic film regardless). How none of the judges noticed that Cha Cha took another girl's (Sandy's) place even after she'd already been "tapped out" is another huge plot hole. Plus a lot of people in America were watching the dance on TV and it's not mentioned by anyone after this scene. 35 years later and that scene still bugs me (haha).
