King Kong Escapes

As a children's film, Toho pressured their 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 Japanese superhero TV shows had the superheroes routinely slice, decapitate, and overall mutilate their monster opponents. However, special effects director Eiji Tsuburaya felt that such violence was inappropriate to show on the big screen and when Toho wanted Gorosaurus to bleed profusely after King Kong tore his jaws apart, Tsuburaya snapped back, saying "These movies are for kids. 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 in the film, Dr. Who's men cast shadows on the painting of the "distance" (mainly snow-capped mountains) on the studio set.

In the version of this film shown on television, Dr. Who's death scene was cut due to its rather gruesome nature. However, the DVD and Blu-ray releases of it are both uncut.
