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: 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)
Continuity mistake: At the start, when Janet catches the bouquet and shouts, "I got it," as she jumps up and down, she holds it in her left hand in the close-up, but in the next shot it's in her right hand. (00:06:15)
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: During 'Dammit Janet', just after Brad draws the heart on the doors, when Janet runs to the stairs her arms are outstretched as she holds the bouquet in her right hand in the close-up, but next shot it's in her left hand. (00:08:25)
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: 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: During "There's a Light" Janet's sweater changes colour. First it's white, then blue, then white, then blue, then white. In the car, it's white, once they get out of the car, it's definitely pale blue from all camera angles and gets slightly darker as it gets wetter, then there's a 7 second shot where it's definitely white, then there's another two shots where it's blue, then they reach the door and it's white for the remainder of the time it's in the movie. It's been suggested that there's colored lighting, but nothing else picks up nearly that amount of blue, i.e. her pink shirt isn't lavender, its white buttons aren't blue, their teeth aren't greenish, etc. (00:13:55 - 00:17:15)
Continuity mistake: Near the beginning of "The Time Warp", we see a male Transylvanian handing a tray of snacks to another Transylvanian (note the b/w socks and shoes) off-screen to the left. In the very next shot, he is holding the tray of snacks and eating a donut. (00:20:35)
Continuity mistake: As Brad and Janet enter the ballroom at the beginning of "The Time Warp", a red carpet runs from the throne at the opposite end of the room, down the steps, and clear across the floor to the ballroom entrance. After the second verse, as Riff Raff and Magenta dance across the floor, the carpet stops short at the bottom of the steps. The full-length carpet reappears and disappears several times during this number. (00:21:30 - 00:22:15)
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: 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: 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 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: 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: After Frank-N-Furter makes his initial appearance, when he bumps into Janet on the way out, her necklace chain is under her large pink dress collar. Once Frank-N-Furter leaves, her chain is actually around her neck now, over the large collar, so Riff Raff can easily pull the dress down unhindered. (00:27:00 - 00:27:50)
Continuity mistake: As Magenta is undressing Brad she throws Columbia his pullover - twice. (00:28:20)
Continuity mistake: When Brad and Janet are in the Throne room, it shows that when Magenta is taking off her blue woolen undercoat her light blue shirt is undone, but when the view comes out wide Columbia then undoes her shirt. (00:28:20)
Continuity mistake: After Brad and Janet arrive at the lab, when Frank-N-Furter holds out his right hand to shake their hands, his left hand holds a champagne glass and the rubber gloves. The gloves go from lying over his pinky, to over his hand, to over the middle finger, between shots. (00:30:10)
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)
Chosen answer: She kicks him in the groin when he has her cornered on the stairway.
