[on the planned U.S. remake of
Superman vuole uccidere Jessie (1966)] "At the Locarno festival, we were approached by an American producer
William L. Snyder who then came straight to Prague, where he himself had produced several animated films years ago. We gave him the rights, he paid us and arranged for us to travel to the US, where we got a hired scriptwriter,
Stu Hample. Before
Milos Macourek and I left, we had time to prepare our own version, and Hample more or less accepted it with some minor variations here and there. Personally, we never got our hands on the final draft of the English script; in 1967 the producer was sending it out to companies and seeking funding, and when he went to Prague again, he was about to finalize the contracts for the filming. But it was just August 1968. So as soon as the Russians arrived, he pulled everything off, got on the first plane and flew back to America. We talked on the phone and corresponded for a while, and even at one point it started to look like it might work out after all, but after awhile the project was over."
