What rare Orson Welles films are on tape that are not on DVD? Only reason I say tape as opposed to DVD is that there might be more films available.
One Man Band?
Any of the films on the Orson Welles Unfinished Works at the film forum?
What about the long interview with the BBC that was aired in the US in the early 90s.
Does anyone own it? Does anyone have the uncut version?
