All Monsters Attack was released theatrically in Japan on December 20, 1969. It received a theatrical release in the United States in 1971 by Maron Films, under the title Godzilla's Revenge, on a double bill with the 1967 film Night of the Big Heat. It has received generally negative reviews for its tone, characters and extensive use of flashback footage from previous Godzilla films; many retrospectively critics and audience consider it to be one of the worst Godzilla films, although Honda viewed it as one of his favorites.
