Vulgar, spirited, and neglected director George Sidney (Bye Bye Birdie, The Eddy Duchin Story, Kiss Me Kate) meets his match with this 1964 Elvis Presley vehicle: Presley, Ann-Margret, and Las Vegas itself are all ready-made for his talents, which mainly have to do with verve and trashy kicks. Unfortunately not as many sparks fly as one might hope. Still there’s Presley as a race car driver who doubles as a singing waiter, and, as critic Tom Milne describes it, “Ann-Margret revs her chassis at him.” There’s also William Demarest and, among the songs, “The Yellow Rose of Texas.”
