Harryhausen worked on a series of fantasy films in the 1960s, most importantly Jason and the Argonauts (1963). Many critics have identified this film as Harryhausen's masterwork for its stop-motion animated statues, skeletons, harpies, hydra, and other mythological creatures. Other Harryhausen fantasy and science fantasy collaborations from the decade include the 1961 adaptation of Jules Verne's Mysterious Island, the critically panned One Million Years B.C. starring Raquel Welch, and The Valley of Gwangi (1969).
Capitalising on the success of the sword and sandal genre several Italian B-movies based on classical myth were made, including Ulysses (1955 film), Hercules Unchained and the Maciste series. Otherwise, the 1960s were almost entirely devoid of fantasy films. The fantasy picture 7 Faces of Dr. Lao, in which Tony Randall portrayed several characters from Greek mythology, was released in 1964. But the 1967 adaptation of the Broadway musical Camelot removed most of the fantasy elements from T. H. White's classic The Once and Future King, on which the musical had been based. The 1960s also saw a new adaption of Haggard's She in 1965 starring Ursula Andress as the immortal "She who must be obeyed" and was followed by a sequel in 1968 The Vengeance of She based loosely on the novel Ayesha: The Return of She both produced by Hammer Film Productions, 1968 also saw the release of Chitty Chitty Bang Bang based on a story by Ian Fleming with a script from Roald Dahl.
