Agutter moved to Hollywood at 21 and appeared in a number of films over the next decade, including The Eagle Has Landed (1976), Logan's Run (1976), Equus (1977, for which she won a BAFTA as Best Supporting Actress), An American Werewolf in London (1981) and an adaptation of the James Herbert novel, The Survivor (1981). Agutter has commented that the innocence of the characters she played in her early films, combined with the costumes and nudity in later adult roles such as Logan's Run, Equus and An American Werewolf in London, are "perfect fantasy fodder".
