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: Before Rocky's unveiling, when Frank-N-Furter is giving his speech, the rubber gloves he is wearing go from being folded, to being straight, and back again. (00:31:30 - 00:33:00)
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: When the color machine has been lowered and Frank has finished opening the spigots, there is a shot which shows his reflection in the monitor on the console where Riff Raff is turning the crank. In the reflection his hands are up in the air, waiting for the color machine to be lowered - which, of course, it already has. (00:35:50)
Continuity mistake: During the song "I Can Make You A Man" as Frank-N-Furter pushes away the vaulting horse, you can see the hand at the right of the screen, pulling the attached wire to assist Tim Curry. (Visible in the theatre and on widescreen DVD - but the TV version crops it.) (00:41:35)
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)
Continuity mistake: 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. (00:42:31)
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: 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 rips the front of her white slip, the ripped strip of cloth is much larger than the bit she places on Rocky in the next shot. (00:55:45)
Continuity mistake: When Tim Curry is about to pull the switch to send Dr. Scott into the room, he starts to lift up his left leg. In the close up, it's his right. (01:01:00)
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: During dinner, on the back of Rocky's chair there's a party hat which keeps switching from being upright to hanging by its elastic over the chair's ball finial, depending on the angle of the shot. (01:03:55)
Continuity mistake: In the dinner scene, Riff Raff pours Dr. Scott's wine in one shot and again two shots later. (01:04:45)
Continuity mistake: Dinner party - Brad's party hat: After serving Dr. Scott's wine, Riff Raff passes by Brad's chair and knocks his hat off the back of the chair so it's hanging by the string. In the next shot showing Brad a few seconds later, it's back to its normal position. (01:04:55)
Continuity mistake: During dinner, when Frank begins to sing Happy Birthday to Rocky, Magenta walks around the table serving the slices of "meat", but in Frank's closeup when he sits down Magenta is still standing beside him. (01:05:30)
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: After Frank-N-Furter carves the "tender" main course, when Riff Raff tosses one piece of 'meat' onto Brad's plate, in the next shot Frank sits down, but when it cuts to the wide shot Riff Raff tosses the piece of meat onto Brad's plate again. (01:05:35)
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)
Continuity mistake: Right before 'Planet Schmanet Janet', look at her slip right after Frank slaps her. In the close up, the back is intact. But in the wider shot, the back is ripped. (01:09:50)
