Corrected entry: The first day of school the Principal invites everyone to the pep rally coming up. After the Pep rally that week all the Pink Ladies and Sandy go to Frenchie's for a party. At this party is when Rizzo leaves and her and Kenickie have their "accident." Yet Rizzo doesn't find out until the carnival at the end of the school year that she's not pregnant. That would have been one heck of a first trimester...
Corrected entry: In the beginning credits, they spell Frenchie with an "ie" but at the end credits, they spell it with a "y".
Correction: Frenchy (which is the correct spelling of her name) is spelled with a "y" in the opening and closing credits.
Corrected entry: In the beginning animated sequence, when Rizzo takes off her top, the long neck in the mirror suddenly disappears altogether.
Correction: The reason why Rizzo's long neck disappears is precisely what is meant to happen. The long neck is a joke about Rizzo and that is why it disappears.
Corrected entry: When Sandy is in her cheerleading outfit, her hair is pulled back at the top of her head in a ponytail. The ponytail is very long. Yet, in the rest of the movie, her hair is short.
Correction: Actually, every time her hair is up in a ponytail (like in the drive-in scene), it is long - fashion at the time included clip-in extensions, so this is realistic.
Corrected entry: At the race, Frenchy is heard asking Marty the question, "What did she give him?" but her mouth isn't moving- in fact, its chewing gum. A common misconception is that Jan is saying this line and not Frenchy, but the voice sounds exactly like Frenchy's and not at all like Jan's.
Correction: If you watch this scene on the DVD widescreen version, you actually see Jan ask Marty this question. Even though it may sound like Frenchie's voice, you can't argue with what's on the screen.
Corrected entry: How is it possible that Cha-Cha and Danny win the dance contest when Danny and Sandy were the only pair left on the floor? Yet nobody noticed the switch?
Correction: The principal does notice. But it doesn't matter, they're still the best dance couple according the judges.
Corrected entry: When Rizzo is shuffling her cards on the first day of school, during the announcements, you can see the string through the cards that keep them together.
Corrected entry: At the Pink Lady sleep over, Frenchy tries to pierce Sandy's ears. She does one ear, and says it bleeds, but when Sandy comes out of the bathroom, both her earlobes are normal. If Frenchy really had made a hole in her ear, it would have been all red. (00:30:10)
Correction: After Frenchy got out of the bathroom she said she only did one ear and she got sick, and when she started to pierce it in her bedroom, she started with the right ear. When Sandy steps out of the bathroom, you only see her left ear, which wouldn't be pierced.
Corrected entry: In the ice cream parlor, when Danny is sitting with his friends and Sandy is on the upper level, eating with Tom, Rizzo comes by, and says "Somebody snaking you, Danny?" She glances and nods her head to the right, but Sandy and Tom are in plain sight over her left shoulder. (00:43:00)
Corrected entry: In the dance scene at the school, Doody can't dance with Frenchy and apparently Jan has trouble dancing as well, but later on nobody seems to be having any trouble dancing.
Correction: Jan can dance. The problem Putzy has is that Jan wants to lead all the time.
Corrected entry: In the end during "We Go Together", there is a scene where Sandy jumps towards Danny and she doesn't have her red Candies shoes on.
Correction: She's holding them in her hands.
Corrected entry: In the pep rally scene where everyone is rushing up to see what Coach Calhoun has to say, you can see a brown-headed girl rush forward, and then you can see a hand reach out and pinch her bottom.
Correction: This is an illusion - the boy is next to the girl, he raises his right hand but it is no where near the girl's bottom, the angle makes it look like he does touch her, also the girl does not react.
Corrected entry: Just at the beginning of the Hand Jive dance off, Patty and Marty are standing in front of the big float figure. The hat tips and paper falls on both of them. In the next shot, as Patty is crying, Marty is no longer there, but there are a couple of guys next to Patty attempting to fix it.
Correction: In the background you see Sonny storming away and Marty following him like she's trying to apologize for a fight they just had.
Corrected entry: During "Sandra Dee", Frenchy's hair is in rollers and a hairnet, then her hair is down when she and the others are turned on their stomachs. At the end, when Sandy comes out of the bathroom, her hair is back in rollers and a hairnet.
Correction: Frenchy's hair is never down during "Sandra Dee, " she's wearing a wig like the rest of the girls.
Corrected entry: During the race at Thunder Road, the cars go up onto the slope where Sandy is sitting, but she cannot be seen at any time during the race scene. She suddenly appears out of nowhere.
Correction: Sandy is not sitting on the race track. She is sitting on the other side of the start bridge. You can tell she was not on the track because the stopped grease lightening car front is facing her. Also when they shoot out she is sitting getting her shoe on and all the parked cars are in view. They did not race past people's cars.
Corrected entry: In the scene where Danny and Sandy rush into the diner, Sandy has a white cardigan draped over her shoulders which she places on the back of her chair. However, when they both leave in a rush she doesn't pick the cardigan up and you cannot see it either on the chair or on the floor.
Correction: She takes the cardigan with her. You can see it in her hand when she leaves.
Corrected entry: In the scene where the T-Birds pull up at Frenchy's the night of the slumber party, the front porch is all along the front of the house & there is nothing in the yard. But when Sandy goes outside and is singing Hopelessly Devoted, it's a small little corner porch and there is a swimming pool in the yard.
Corrected entry: During "We Go Together" when John Travolta jumps into the shot from the right, followed by Olivia from the left, you can see that Olivia has removed her high heels to jump into the shot. The shoes are on in the previous shot and in the following shot.
Correction: No they aren't. She is holding them in her hands as they are running off, which is the very next shot after she jumps into the scene, and after she and Danny run off, you don't see her again until they are driving off in the car, and then you don't see her feet at all.
Corrected entry: During 'You're The One That I Want,' Danny falls at the feet of Sandy. When he gets up, you can see dirt on Danny's black shirt, but when they go into the funhouse, the dirt disappears.
Correction: The dirt was probably brushed off before he got into the funhouse.
Corrected entry: A lot of the songs that are played at the dance are songs that are in the stage version but weren't included as "character" songs in the film. For instance, the song Danny sings along to at the dance, "Those Magic Changes", is sung by Sonny in the stage version.
Correction: 'Those Magic Changes' is actually sung by Doody in the stage version.
Correction: It is safe to assume that Rizzo and Kenickie had been dating throughout the entire school year.
