Danny Kaye plays the first of his cinematic dual roles in Goldwyns Wonder Man. Kaye appears as timid librarian Edwin Dingle and Edwins extroverted twin brother, nightclub entertainer Buzzy Bellew. When Buzzy witnesses a gangland shooting, he himself is rubbed out by mob boss Ten-Grand Jackson (Steve Cochran, in his movie debut). Before long, Edwin is visited by Buzzys ghost, who persuades his bookish brother to help bring Jackson to justice. For the rest of the film, poor Edwin is possessed by his brothers sportive spirit, causing no end of confusion for Edwins demure lady friend Ellen Shanley (Virginia Mayo) and Buzzys more outgoing girlfriend, dancer Midge Mallon (Vera-Ellen, also making her first film appearance). Done up in splashy Technicolor, Wonder Man is perhaps Kayes best Goldwyn-produced vehicle, permitting him to play a character (or characters) rather than a caricature. Highlights include an opera spoof (a variation of which showed up in Kayes 1954 feature Knock on Wood), Dannys allergic rendition of Otchi Chornya, and a wonderful vignette wherein Kaye imitates all the inhabitants of a pet shop. ~ Hal Erickson, All Movie Guide
