The five films of the original series (1968–1973) have become cult classics. Boulle, who had thought his novel to be unfilmable, was taken by surprise at the worldwide success and impact of the film. He wrote a script for a sequel titled Planet of the Men, but the producers of the original film turned it down. The second film, Beneath the Planet of the Apes, which came out in 1970, was also very successful. It was followed by Escape from the Planet of the Apes in 1971, Conquest of the Planet of the Apes in 1972, and Battle for the Planet of the Apes in 1973.
