When John Beck sold the "King Kong vs Prometheus" script to Toho (which became "King Kong vs. Godzilla"), he was given exclusive rights to produce a version of the film for release in non-Asian territories. He was able to line up a couple of potential distributors in Warner Bros. and Universal-International even before the film began production. Beck, accompanied by two Warner Bros. representatives, attended at least two private screenings of the film on the Toho Studios lot before it was released in Japan.
