Continuity mistake: During "Hot Patootie", before Eddie drives up onto the ramp, there is a group shot of the Transylvanians dancing. Two of them disappear from one shot to another. The black guy and the Arab can be seen kicking out during the line up but when the camera changes to the wide shot of them all they are both gone.
Continuity mistake: Near the beginning of the movie, in the "wedding scene," when we first see the little camera man his camera has an old fashioned flash (a round metal dish with a flashbulb inside). When he takes the wedding photo, the camera has a modern electronic flash on it. (00:05:00)
Continuity mistake: While riding his motorcycle around the lab during the "Hot Patootie" number, notice how Eddie's black eye and cut changes sides in two of the flipped close-ups. (00:44:30)
Continuity mistake: When Janet is fainting after Frank comes down the elevator, she is lifting up one hand. In the close-up it's the other hand. (00:24:25)
Continuity mistake: When Frank-N-Furter steps out of the pool, the heart 'tattoo' on his right upper arm (deltoid area) is smudged and runny, but is near perfect in a following shot.
Continuity mistake: During the dinner scene, there's a party hat on the back of Janet's chair. It disappears in one shot. (01:05:35)
Continuity mistake: When Ralph and Betty drive off in the car, the positions of the surrounding family and friends noticeably change between shots, such as the elderly couple who stand near the church sign.
Continuity mistake: During 'Hot Patootie, as Eddie and Columbia canoodle on the floor, when the guests dance on the upper level their positions in the line change between shots. (00:44:10)
Continuity mistake: At the beginning of Columbia's solo in "The Time Warp" she is sitting on the jukebox and wearing her gold glitter hat. Then, during the refrain, we see the hat on the floor near the jukebox, sans Columbia. Immediately after the refrain, Columbia has her hat back on as she does her tap dance. [There's about 9 seconds that Columbia's off-screen that she could have retrieved it, and about 4 seconds Magenta and Riff Raff are off-screen and end up next to Columbia and could have picked it up and given it to her, but there's no reason for it to have been out in the middle of the floor to begin with.] (00:22:10)
Continuity mistake: Before Frank-N-Furter kills Eddie, his painted black eyebrows are curved with pointed angles above his eyes, but when he explains to Rocky about the mercy killing, his painted eyebrows have a rounded arc shape to them.
Continuity mistake: In the scene where Brad and Janet first talk with Frank in the lab (before Frank's speech beginning with 'Tonight, my unconventional conventionalists...'), Frank makes a comment about how Brad is "so dominant." At that moment, Brad closes his robe but does not button it. However, when the camera switches angles, it is buttoned. (00:31:33)
Continuity mistake: At the beginning when Brad and Janet get the flat tyre and it's raining, Brad says "Didn't we pass a castle back down the road a few miles?" before they get out of the car to go to the castle. If the castle was a few miles back, both of them should be soaking wet, and the paper Janet put over her head should have been soaked not long after they got out of the car. After they enter the driveway of the castle they get increasingly wet, but they are barely damp before this despite walking some distance in the constant rain. (00:13:25 - 00:14:25)
Continuity mistake: When Brad and Janet first enter Frank-N-Furter's laboratory, Janet's shirt is buttoned when she is hanging on Brad. When she twirls around to stand on his other side, her shirt opens during the turn, but as soon as she stops, it is buttoned up again. (00:30:35)
Continuity mistake: As Magenta is undressing Brad she throws Columbia his pullover - twice. (00:28:20)
Continuity mistake: The words 'love' and 'hate', which appear on Eddie's knuckles in the close-up when he mounts his motorbike, disappear in other shots where we see his hands.
Continuity mistake: During the song "Dammit Janet", as Brad presents the ring to Janet, her purse is behind her at the top of the church steps. A few seconds later, the purse has moved to the left of her feet. (00:08:40)
Continuity mistake: During "Sweet Transvestite", Frank throws his cape off onto the throne. Part of the cape is over the left side of the back of the throne and the front of the left arm of the throne is not covered at all. There's a cut to Brad & Janet, then when it cuts back to Frank the cape is evenly draped over both arms of the throne covering them all the way to the floor with none on the back. (00:25:15)
Continuity mistake: When Frank-N-Furter is talking to Dr. Scott just before he reveals his relation to Brad, Furter's right leg goes from being on the arm of the chair Dr. Scott is sitting in to a standing position from shot to shot. (01:01:50)
Continuity mistake: When Frank is first descending in the elevator, he is tapping his foot to the beat. In the close-up, he seems to be just barely lifting his heel just a few inches from his other foot, but on the wider shots, his foot is lifting MUCH higher and about a foot apart. (00:24:05)
Continuity mistake: When Brad, Dr. Scott, and Janet are turned into stone, their clothes fall to the ground. Dr. Scott's and Janet's clothes turn to stone, but Brad's remain cloth. When Columbia and Rocky are turned to stone, Columbia's clothes completely disappear (there is nothing around her feet when they are shown a few shots later). We never get to see if Rocky's are cloth, stone or nothing. (01:12:30)
Chosen answer: She kicks him in the groin when he has her cornered on the stairway.
