Christopher Lee has said about this movie: "Some of the films I've been in I regret making. I got conned into making these pictures in almost every case by people who lied to me. Some years ago, I got a call from my producers saying that they were sending me a script and that five very distinguished American actors were also going to be in the film. Actors like José Ferrer, Dean Jagger, and John Carradine. So I thought "Well, that's all right by me". But it turned out it was a complete lie. Appropriately the film was called End Of The World."
