King Kong - Jättiläishirviö

As a children's film, Toho pressured the filmmakers to show more gore in the monster fights. Children's media in Japan at the time was showing increasing amounts of violence, especially when compared to the rest of the world. Films from rival studios would should monsters frequently bleeding while popular superhero TV shows had the heroes routinely slice, decapitate, and overall mutilate their monsters opponents. However, effects director Tsuburaya felt that such violence was inappropriate to show on the big screen and when the studio wanted Gorosaurus to bleed profusely after Kong broke his jaw, Tsuburaya snapped back. "These movies are for kids," he said, "Why do you enjoy showing them blood?" The compromise was for Gorosaurus to foam at the mouth instead.

During some of the North Pole scenes, Dr. Hu's men cast shadows on the painting of the "distance" (mainly snow-capped mountains) on the studio set.

The version of the film shown on television deleted Dr. Who's death scene due to its rather gruesome nature. However, it was restored in the DVD release.
