King Kong vs. Godzilla
In one of his earliest animation jobs, a young Hayao Miyazaki worked on this film as an in-between artist. His contribution to the ending of the film brought Miyazaki to the attention of Toei. The screenplay was written by Shinichi Sekizawa, the writer of the first "Mothra" (1961). Sekizawa also contributed screenplays to some of the most popular films in the Godzilla series from "King Kong vs. Godzilla" (1962), to "Godzilla vs. Mechagodzilla" (1974), including "Mothra vs. Godzilla" (1964).
