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)
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)
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)
Visible crew/equipment: Just after Brad says, "I really love the skillful way you beat the other girls to the bride's bouquet," as 'Dammit Janet' begins, twice it cuts to a shot of the "church caretakers" standing idly in front of the doors. In these two shots their marks are visible at their feet; there are outlines on the ground around their shoes, which vanish in following shots. (00:07:50)
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)
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.
