The World's Greatest Lover is a 1977 American parody film directed, written by and starring Gene Wilder, and co-starring Carol Kane and Dom DeLuise.

Led by studio head Adolph Zitz, they decide to hold a contest for the World's Greatest Lover in order to find a star to combat Valentino's popularity.

Vincent Canby of The New York Times described the film as not only "frequently side-splitting," but "uncommonly handsome" for a comedy, "the period sets and costumes having a lot of the fantasy quality of a stylish Broadway musical.

"[6] Arthur D. Murphy of Variety called the film "a good period comedy," adding, "This time the individual sketchpieces ... emerge as varyingly humorous episodes strung out on a skimpy story line.

Most unsettling of all is Wilder's own brand of rampaging comic hysteria, which here goes disastrously unchecked ... and augmented by the similar excesses of Dom DeLuise, Fritz Feld and Carl Ballantine, generates more decibels than laughs.
