City Under the Sea (released as War-Gods of the Deep in USA) is a 1965 science fiction film. It was directed by Jacques Tourneur (his final film) and starred Vincent Price, Tab Hunter and David Tomlinson.
The plot concerns the discovery of a lost city beneath the sea off the coast of Cornwall. Price is the captain overseeing a group of sailors who have lived there for more than a century where the peculiar mix of gases has allowed them to extend their lifespan.
The film was made in the tradition of the period fantasies started with Disney's 20,000 Leagues Under the Sea (1954). The film attempted to capitalize on the series of Edgar Allan Poe films that had been made by Roger Corman, starring Price. To this extent the film took the title of a Poe poem, "The City in the Sea", and attempted to exploit the Poe films trend, even though the film is only loosely based on the poem with a recitation of the poem at the end of the film.
