Creator Backlash: Susan Sarandon refuses to talk about the movie, but not for the usual reasons. It's because she hates the fact that none of the cast members get royalties from the DVD sales.
Tim Curry was very reluctant to talk about the film for years and even told VH-1 that he grew "chubby and plain" in order to try and escape the role. These days, he's more open to talk about the film and even sees it as a "Rite of passage" for teenagers.
Peter Hinwood (Rocky) is only slightly embarrassed by being in the film. Contrary to popular rumor, he's never thrown anyone out of his shop for talking about the film. He only sees the film as a "part of the past" and rarely talks about it.
Development Hell: Richard O'Brien has been mulling over making a direct sequel to the original stage show for years. However, so far, all that's been seen are a few scrapped scripts and a vague concept that involves Frank coming back to life, though he's apparently written the first act to the sequel.
In one of the stage play versions, Giles (Anthony Head)played Frank N Furter. The still shots and the track of Anthony singing Sweet Transvestite are widely viewable online. And made this troper really want to work it into a Giles flashback fic, since it would totally disturb the Scoobies.
