In one of his most popular movies, Elvis Presley shared the screen with Ann-Margret in Sin City , aka Las Vegas , easily creating the most electrifying teaming Elvis had on-screen. Hes Lucky Jackson, a Grand Prix race driver working at a casino to raise cash for a new engine; shes a hotel swimming instructor - and the romantic action revs up from their first meeting. Veteran director George Sidney, who guided Ann-Margret in the prior years Bye Bye Birdie, combines the hormonal heat wave with fascinating sights of 60s Las Vegas . Songs include the high-roller title track, the stars duet on The Lady Loves Me, her sultry Appreciation and The Kings version of Ray Charles Whatd I Say.
