Corrected entry: At the climax to the drag race, when Danny jumps the puddle and takes the lead, as his car hits the pavement in slow-motion, you can see that the car literally falls apart (the bumpers fall off and the hood pops open). In the next shot, the car's in perfect shape again.
Corrected entry: In the Greased Lightning scene when Danny starts singing he throws his jacket behind him and you can see it land on top of a cupboard behind him. When they all go behind the car you can see the same cupboard but the jacket isn't on top of it.
Correction: It gradually slipped off the cabinet as they were going behind the car.
Corrected entry: In "Greased Lightning," when John Travolta is lifted up by a chain to get the motor, he has no leather jacket; when he comes back down with the motor, he now has his T Bird jacket back on that he threw off earlier.
Correction: "Greased Lightning" is a fantasy sequence, which like dream sequences, are not bound by the standard laws of convention.
Corrected entry: In the drive-in scene, just after Sandy has rejected Danny and slammed the car door into his privates, look very closely at the car door. At the end of the movie, we see the car is a bright red colour which is covered with lots of dust during the rest of the movie. In this series of shots you can see 'John's' written into the dust (using a finger, obviously) on the car door, obviously referring to John Travolta. This is best seen in the digitally remastered version.
Correction: It actually says James (the s is on the front fender).
Correction: This is not exactly a mistake. True it is oddly coincidental that the name John would be written, but it is possible that someone at the drive-in signed their name in the dust.
Corrected entry: In the last song there is a shot over the fairground which shows a spinning rotor cage full of people. Back on the ground two seconds later the rotor cage is clearly visible in the background and obviously empty.
Correction: "We Go Together" is a montage of the carnival, not a true-to-the-minute depiction of time. (As evidenced by Jan and Doody "jumping" onto one of the rides and back off within a matter of seconds.) However, even with that, the rotor cage has time to land and empty between shots.
Corrected entry: Kenickie was supposed to sing the 'Grease Lightening' song but John Travolta was given the part because he wanted it.
Corrected entry: In the Beauty School Dropout song, Rizzo, Jan and Marty are part of the singers. Toward the end of the song, while holding a long note, Rizzo stops singing and looks away, then starts singing again.
Correction: This is a guilty reaction to a line in the song, "Get off the pot." It's subtle, but definitely meant to happen, and not a mistake.
Correction: The only thing that happened was the hood and trunk popped up - they could of easily went back into place without anybody fixing it.
