The movie included such scenes as Dracula and his conquest dancing to "I Love the Nightlife" at a disco.The film's box-office success created a popularity surge for Hamilton, who also served as executive producer.After appearing in a production of A Farewell to Arms (1966) on TV, he returned to MGM to make a romantic comedy with Sandra Dee, Doctor, You've Got to Be Kidding! At Columbia he co-starred with Glenn Ford in a Western A Time for Killing (1967), originally directed by Roger Corman then Phil Karlson.Hamilton played a cat burglar in MGM's Jack of Diamonds (1967).
MGM tried to change his image by putting him in a Western, A Thunder of Drums (1961) alongside Richard Boone; the film was mildly popular.Bo Derek writes in her autobiography "there was an ongoing contest between John [Derek] and George Hamilton as to who was tanner". Although shot in 1958 it was not released until the following year. Hamilton supported Natalie Wood and Robert Wagner in another melodrama, All the Fine Young Cannibals (1960). Hamilton's next film was far more popular, the beach party comedy Where the Boys Are (1960).
