Plot hole: After Dr. Scott exposes Frank + company as aliens, Frank replies 'Go on, Dr. Scott. Or should I say, Dr. VON Scott.' Brad is outraged, but it doesn't make much sense. Why would it be so shocking to hear that he has a German surname? He's spoken with a German accent throughout the movie. Simply stating his real name wouldn't imply that Dr. Scott is a Nazi. It is obvious that he is German. Richard O'Brien (creator of Rocky Horror) even states on the DVD commentary that he's always disagreed on this being in the film.

Continuity: Right before Planet Schmanet Janet, look at her slip right after Frank slaps her. In the close up, the back is in tact. But in the wider shot, the back is ripped.

Continuity: As Frank leaves the pool and sings "I'm going home", his makeup is clearly running all over his face, in the next shot it is perfect again.

Continuity: 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.

Continuity: 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.

Continuity: 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.

Audio problem: In the scene as Frank-N-Furter exits the elevator to start to singing Sweet Transvestite, Janet faints but keeps screaming ever after she has passed out.

Continuity: 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.

Deliberate "mistake": Before the floor scene starts Dr. Scott does not have on the fishnet stockings. As he rolls across the stage the stockings are back.

Continuity: 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.

Continuity: 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.

Continuity: 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.]

Continuity: During the first verse of Eddie's song, you can see Frank standing in the background (right before Eddie goes over to sing to Rocky). In the next shot it shows Frank leaning against the wall.

Revealing: During Sweet Transvestite, when Frank goes to get a drink of water, watch closely. You can see the screen shake a little bit. This leads me to believe that the cameraman tripped.

Continuity: If you look closely in the dinner scene, Riff Raff serves Brad his meat 2 times.

Continuity: In "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 2 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, it's white buttons aren't blue, their teeth aren't greenish, etc.

Continuity: When Brad and Janet are in the Throne room, it shows that when Magenta is taking off his blue woolen undercoat his light blue shirt is undone, but when the view comes out wide Columbia then undoes his shirt.

Other: At the end of the movie when the castle shoots into space, if you look just as it gets really misty, in the background (it's maybe just centimetres off) you can see the real castle. The one that blasts off is a cutout.

Plot hole: Brad, Janet, Dr. Scott, Columbia, and Rocky are turned into naked stone statues. At the beginning of "Rose Tint My World" the statues are in the same positions but somehow have been dressed. Multiple impossibilities: all are wearing high-heels despite being frozen "flat-footed", the gloves have a loop that goes over the index finger despite all of them making a solid fist on that hand except Janet whose fingers are completely solidly entangled in her hair, all of Dr. Scott's clothes have been put on him despite being attached to the wheelchair in back and his legs covered with the stone blanket.
