Double Trouble on AllMovie

Elvis Presley plays Guy Lambert, a musician (so far, so good) who is touring Great Britain (something Elvis never managed in real life). Jill Conway (Annette Day), a wealthy heiress, is a big fan of Guy's who has developed a very serious crush on him; her family wants to keep her away from the romantically-inclined singer, so they send her to Belgium, not realizing that Guy has a string of gigs set up there. En route to Brussels, a pair of hapless jewel thieves (Norman Rossington and Chips Rafferty) hide their loot in Guy's luggage, which makes the singer the unwitting target of three equally inept detectives (Harry, Herbert, and Sylvester Wiere). While wooing Jill and avoiding her treacherous uncle Gerald (John Williams), Guy also finds himself pursued by the worldly Claire Dunham (Yvonne Romain). Elvis sings nine songs along the way, including "Long Legged Girls with Short Dresses On" and "Baby, if You Give Me All Your Love." 18 months after Double Trouble was released, Presley's career was revitalized by his 1968 comeback special, though he would also release four more films before it aired.
