If there is no validity then where is the public challenge of Lucas stance.
I know of no other case where a director has tried to systematically erase a set of films from existence or tried to rewrite history.
Lucas is such a giant in the industry nobody will challenge him not even his peers.
I mean come on the Murnau foundation can all but restore the original Metropolis once thought lost but a relatively modern film from 1977 is lost by the director himself, its ludicrous.
