Neon nights, tumbling dice, leggy showgirls - it's Vegas baby, and you ain't nothin' but a hounddog if the glittery thought of it doesn't have you belting out Viva Las Vegas! In one of his most popular movies, Elvis Presley teams with Ann-Margret in the fun capital of America. He's a Grand Prix driver and she's a hotel swimming instructor and radiators are on overboil from their first meeting. Veteran director George Sidney, who guided Ann-Margret in the prior year's Bye Bye Birdie, combines the hormonal heat wave with fascinating sights of 60's Las Vegas. Songs include the high-roller title track, the stars' duet on The Lady Loves Me, her sultry Appreciation and the King's What'd I Say.
