Even the stars who were most famous for being famous made some worthwhile films - here are some examples.
Zsa Zsa Gabor: Although she can't really be credited as a major factor for its success, Touch of Evil (1958) is probably Zsa Zsa Gabor's best known and most respected film. She plays a strip-club owner in writer-director-star Orson Welles' crime film - with a couple of amazing long takes - about a newlywed Mexican cop (Charlton Heston) and his involvement with a corrupt sheriff (Welles) after a car explodes on the US-Mexican border. Other stars in small roles include Marlene Dietrich and Mercedes McCambridge.
George Hamilton: The actor spoofed his suave screen image in two comedies: Zorro: the Gay Blade aka Zorro Swings Again! (1981) in which he played Don Diego aka Zorro and his twin brother Bunny; and comedy Love at First Bite (1979) playing Count Dracula, who in the (then) present travels to New York in search of a fashion model he believes to be the reincarnation of his lost love. In both films he wore a black cape.
Diana Dors: The British actress made a wide range of movies including sex comedies but two of her more memorable are horror films. In Berserk (1967) she plays half of a saw-a-woman-in-two act in a circus owned by Joan Crawford where a series of murders of the employees is taking place. Theatre of Blood (1973) has actor Edward Lionheart (Vincent Price) wreaking vengeance in various Shakespearean ways on the critics who denied him an award. In an Othello-like scenario, Dors plays the ill-fated wife of one of those critics (Jack Hawkins).
Joan Collins: One of Collins' most memorable film roles was in Tales from the Crypt (1972), based on EC Comics' darkly humorous tales. In And All Through the House, she plays a woman who, on Christmas Eve, murders her husband with a poker then finds herself being stalked by an escaped maniac from an insane asylum who is dressed as Santa Claus. Tales that Witness Madness (1973) sees her in an even more bizarre story: Mel is about a woman whose husband brings home a possessed tree that becomes a romantic rival. She also played the lady-in-waiting of Queen Elizabeth I (Bette Davis) in The Virgin Queen (1955).
