Corrected entry: 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.
Corrected entry: When Brad and Janet's station wagon gets a flat tire, the light in the car is a bright white that is emanating from the floor (note the shadows above them and the ones on their faces). If the light was from the dashboard or dome light, it would be more yellow and cast downward shadows on their faces.
Corrected entry: With seconds to go before the castle takes off like a rocket and disappears, Brad and Janet carry the lame Dr. Scott out the front door. After the house disappears, we see pieces of Dr. Scott's wheelchair among the rubble. Did they really push the wheelchair out the door before getting out themselves, with their lives at stake and almost no time to spare?
Corrected entry: I am not sure if this only happens only in the DVD, but at the end when all of them are dancing Columbia's boob pops out and she keeps dancing like that.
Corrected entry: In the first shot of the dinner scene, we can see there are already wet drink stains on the table, even before the drinks have been poured. Later, we see Riff-Raff and Magenta lazily pouring drinks (into the guests empty glasses)and spilling the juice/wine on the table. How could there be drink stains on the table if the drinks hadn't been poured yet? It's obviously an editing mistake...
Corrected entry: During Hot Patootie, Eddy is not wearing suspenders when he's rolling on the ground with Columbia. However, when he's chased into the wine cellar, you can see his red suspenders.
Corrected entry: At the part of the movie when Magenta and Riff Raff are singing the beginning of the Time Warp the clock shows 6:00 (and rings seven times). After the Time Warp they are going onto the elevator and if you listen the clock rings 10 times. No wonder everyone collapses after, they danced for 4 hours, although the song is less than five minutes long.
