In The Great Lover, Bob Hope plays "Boy Rangers" scoutmaster Freddie Hunter, who accompanies his young charges on a European tour. During the ocean voyage to the continent, Freddie falls under the influence of erudite cardsharp O. J. Dabney (Roland Young), who promotes a romance between Freddie and Duchess Alexandria (Rhonda Fleming), the daughter of chronic gambler Grand Duke Maximillian (Roland Culver). What Freddie doesn't know (but the audience does) is that Dabney is not only a crook, but a murderer. Musical highlights include the peppy romantic ballad "A Thousand Violins," delivered by a delightfully intoxicated Rhonda Fleming. Watch for cameos by George "Superman" Reeves and Jack Benny.
