Grease (1978) - 61 mistakes

Continuity: In the pre-credits sequence, when Danny and Sandy on walking on the beach, Danny is on the left and Sandy is on the right. However, in the next scene, when they kiss, they have suddenly changed positions.

Continuity: During the song Summer Lovin', Rizzo lies down on her side on a picnic bench and puts on sunglasses. In the next shot, when she kicks Sandy and another girl off the bench, the sunglasses are off. In the following shot, they are on again.

Continuity: Sandy walks over to meet the girls after doing a cartwheel. On Sandy's cheerleading uniform, there is a LONG red string right next to the letter on her shirt. Then, suddenly, the string disappears in the very next shot.

Continuity: During the slumber party at Frenchie's, when Rizzo brings out the wine, check out the junk on the headboard. Later in the scene when Marty is putting on her robe, the headboard is clear and now has a black fan on the left. Then even later when Jan says "You ain't getting your hands on my ears" the headboard is cluttered again, with the black fan too.

Continuity: In the Greased Lightning dance scene, look just in front of the last white desk on the right side during the dream car segment. One of the dancers knocks a tyre off a stand and it falls in front of the desk. A shot or two later, the tyre is back up on the stand.

Other: In the scene where Sandie is at the shop with the jock, then she goes to the jukebox, the picture behind the jock is all blurred out. You can tell it is a Coke sign - obviously a clash of sponsors.

Continuity: There is a scene in which Danny falls over a hurdle. If you watch his falling frame by frame you will notice that only his right leg is stretched first. Then the camera angle changes and suddenly his left leg is stretched, while the right one is bent.

Continuity: When Kenickie says to Rizzo in the soda parlour, "How about if I finish with you, huh?" there is a tomato ketchup squeezer on his side of the table. In the next scene when Rizzo says, "Finish this!" and throws the glass of cherry soda at Kenickie, the ketchup squeezer has moved to her side of the table, and in the next scene, when Kenickie is covered in soda, the ketchup squeezer is back in its normal position.

Revealing: In the soda shop, the waitress turns off the lights with her elbow because her hands are full, but she misses the light switch by 6 inches.

Continuity: At the beginning of the National Bandstand scene you see people filling the hat of the big "Rydell Ranger" figure with pieces of paper. During the next ten minutes the figure is often visible in the background and the hat is empty - nobody emptied it. After those ten minutes the hat has paper again and is then emptied.

Continuity: Once during the dancing scene you can see Vince Fontaine standing on Marty's left side, and then suddenly on her right.

Continuity: When Cha-Cha receives the award from Principal McGee at the end of "Born to Hand Jive" at the National Dance Off, Putzie is giving Jan a piggy-back next to the Principal. However, in the next scene, Putzie is giving Jan a piggy-back right next to Cha-Cha.

Continuity: At Frenchie's sleepover when they are talking about piercing Sandy's ears, it shows Sandy holding the wine bottle and passing it to Jan. Then it cuts back to Sandy and she is still holding the wine, then it cuts back to Jan and she has the wine again.

Audio problem: During "We go together" at the end of Grease, John Travolta's mouth is not in sync with the words.

Continuity: At the dance, there's a scene where everyone started dancing after Cha-Cha and Danny won the trophy. Well Marty comes in from the side of the screen and lands on the floor in some kind of split, and you can clearly see she is wearing knee pads.

Continuity: In the middle of the dance contest, Patty Simcox does a funny front walkover, and comes dancing towards the camera. Over her shoulder, you can see Sonny running up behind her. But suddenly it cuts to another angle, and someone else is running up behind her to lift up her dress, and Sonny is nowhere to be seen.

Continuity: In "We go together" they all dance forwards. When the camera changes angle Frenchy and Doody have switched sides.

Continuity: In the scene where the whole gang is eating at the soda shop, everybody starts leaving. Doody is in the back, in the middle, on the railing. He's getting ready to leave, takes a bite of his ice cream and sets it down. In the next shot, he sets it down again.

Factual error: When the Pink Ladies are walking Sandy into the outdoor cafeteria, just after she tells them the name of the boy she met last summer, all the cars in the background are from the 70's, not from the late 50's or early 60's. This actually happens twice in the same scene.

Continuity: When Kenickie is first shown, he has two charms on his necklace. One is a small square one, the other is a star inside a circle. The camera cuts to Zuko, then when it cuts back to Kenickie, the square charm is gone. It reappears in a couple of scenes later in the movie, then disappears again.
