Visible crew/equipment: Just as Eddie rides his motorcycle down from the lab's upper level, in the shot from behind him, set equipment and a few crew members are seen gathered at the top right of the screen, just before the shot cuts away. (00:44:40)
Continuity mistake: When Eddie escapes the deep freeze, he wears three rings on his left hand: his middle, ring and pinkie fingers. Bizarrely, the pinkie ring actually disappears in quite a few shots, including when Eddie plays the sax and when he lifts Columbia, just before they mess around on the floor. (00:42:30)
Factual error: The criminologist describes the events of the movie as taking place "on a late November evening". In the very next scene, Brad and Janet are driving in Brad's car, and President Richard Nixon's resignation speech is playing on the radio. Nixon resigned in August of 1974. (00:12:00)
Suggested correction: It is said by the writer of the movie that Brad taped the Nixon speech so he could listen to it later in his car, the movie does take place in late November.
Continuity mistake: In the lab, during 'Hot Patootie', Eddie wears red suspenders clasped to his jeans. When he lies on top of Columbia, both back suspender clasps come undone, though the front clasps are still intact. In following shots both of Eddie's back clasps are on properly.
Visible crew/equipment: In the lab, as Eddie rides his motorcycle on the upper level, in the shot from behind him, the large rectangular reflector/light screen is visible down below to his right. It is angled up, facing the upper level as he rides past. (00:44:35)
Revealing mistake: When Rocky climbs the RKO tower, he carries lifeless Frank-N-Furter on his back. In the wideshots facing the stunt doubles' backs, while Rocky has both of his hands on the tower, the very much dead Frank-N-Furter has his right arm firmly around Rocky's neck to hang on.
Continuity mistake: During dinner, when Frank-N-Furter pulls off the tablecloth revealing the corpse, in the first close-up the platter of carved "meat" is quite gone, but it reappears in the next shot. (01:09:30)
Revealing mistake: When Riff Raff and Magenta burst in after Frank's song, Janet steps away from Frank's side into Brad's arms. Watch Brad's face - you can clearly see the look of pain, as Janet steps on his foot in four inch spike heels. (01:24:55)
Revealing mistake: Funny how when Brad and Janet are led to separate rooms, their rooms are identical, right down to the folds in the chair material and missing drapery tassle fringes...
Revealing mistake: Just minutes after Rocky's creation, when he is lifted out of the tank, there is a nice close-up of Rocky's face. The newly created man with the "Charles Atlas seal of approval" has a few silver fillings in his upper right teeth, which are easily visible as he sings, "Over my head and I've got the feeling..."
Revealing mistake: When Dr. Scott is being pulled through the castle by the Triple Contact Electro-Magnet, you can see the cable and the cut in the carpet, that the cable runs under, pulling his wheelchair at the top of one of the staircases. (01:01:00)
Revealing mistake: When Rocky lifts Frank-N-Furter's body Rocky is barefoot, wearing only the stockings. When Rocky is climbing the RKO tower, carrying his creator, evidently Rocky is wearing a type of thin shoes under his stockings. The stunt double did this as a safety precaution. (01:30:35)
Revealing mistake: The saxophone Eddie plays in "Hot Patootie" has no reed. (00:43:10)
Visible crew/equipment: When the newlyweds leave, just as Ralph and Betty drive their car towards the camera, the reflection of the boom mic/pole is visible on the car's windshield. (00:06:40)
Continuity mistake: After Frank kisses Janet's hand, as she puts it back by her side you can see his lipstick on it. When she reaches out to take the shirt from Brad, Frank's lipstick mark is gone. (00:30:20)
Continuity mistake: After Frank-N-Furter gets out of the pool, and is being threatened by Riff with the anti-matter laser, the tattoo on his upper left torso seems to have mysteriously washed off. It's running and illegible. Also earlier, when he's still in the pool, there's barely a smudge, but when he first gets out it's quite clear. (01:24:55)
Audio problem: During "I Can Make You A Man," when Frank slides his finger down Rocky's chest while saying "ste-he-he-he-heam," you can hear a solitary beep from out of nowhere, from when the synthesizer was hit accidentally during that part of the song and was never edited out (it is on the CD too). (00:40:32)
Continuity mistake: When Brad draws the heart on the church door in the close-up, it's a different shape in the following wide shot. (00:08:25)
Continuity mistake: After the "Time Warp" while they are showing the characters lying on the floor, you can see Janet starting to say her lines in the background. (00:23:30)
Continuity mistake: At the beginning of the film, just after the wedding photo is taken we see the father of the bride run up the church steps. Seconds later, we see him running up the steps again. (00:05:40)
