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)
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)
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: 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)
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: 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: 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: 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)
Trivia: This movie premiered in the US at the end of summer '75, following the blockbuster premiere of Jaws in June '75. When the studio created theatrical posters for The Rocky Horror Picture Show, one was a send-up with the caption, "A different set of jaws" under the big red lips.
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)
Visible crew/equipment: When Eddie rides his motorcycle on the lab's upper level, in the second shot from behind him, just as he veers a bit to his left, the equipment attached in front of the windshield becomes visible (at the left). It's gone in other shots. (00:44:35)
Trivia: A life-size bronze statue of Riff Raff dressed in the finale's space suit was erected in Hamilton, New Zealand in 2004, in a tribute to RHPS creator/writer Richard O'Brien. The following is inscribed on the plaque: "It's astounding! Where we stand is the birthplace of the Rocky Horror Picture Show. On this site stood the Embassy Theatre, the home of Hamilton's Late Night Double Feature show, and the barber shop where Richard O'Brien cut hair and daydreamed from 1959 to 1964." WETA Workshops, of Lord of the Rings fame, designed the statue.
Other mistake: After Frank releases Dr. Scott from the Triple Contact Electro Magnet, Janet and Rocky are heard giggling in Rocky's birthtank. As Frank walks over to the tank, the right magnet pops out again just before it goes off-screen. (01:02:45)
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: 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)
Chosen answer: She kicks him in the groin when he has her cornered on the stairway.
