Found out some very interesting things. Alex is a nice guy. He has a British accent, which surprised me since his father didn't - but growing up in London I can see how that would happen.
He confirms that Disney bought everything - the negatives, the artwork, the whole film. Alex himself doesn't have much, but he does have the original drawings for King Nod and Zigzag talking - "Death and destruction, Zigzag!" The well-known shot seen in the documentaries.
As of 2001, the drawings were stored in a bunker in Burbank. He went there personally to check it out.
He confirms that Dick won't talk about the film because it "destroyed his life."
Alex has no love for Fred Calvert, and has never met him. He would have nothing good to say to him.
He was trying to get Disney to release a proper DVD of The Thief as early as 1993. Howard Green, publicity person at Disney and "nice guy" was trying to make it happen over the years, as was Roy Disney. It's never happened, and Alex feels it's never going to happen.
He confirms the rumors that Dick has been working for some years now on a new feature film - working on it basically alone, with a tiny staff. Neither he nor Alex will discuss the exact details of the film for Obvious Personal Reasons. That makes me glad though.
