Clambake (1967) DVD

Elvis Presley sizzles as a lovelorn million-heir in this riveting and romantic rock 'n' roll romp. Vying for the attentions of the lovely Shelley Fabares, Elvis finds himself caught up in a rivalry with playboy Bill Bixby against a tuneful background of comedy, romance and speedboat racing! Clambake is pleasing escape entertainment and the wildest party to hit the beach since they invented the beach ball!

It's a hip version of The Prince and the Pauper as Elvis relinquishes his oil-baron father's fortune and trades identities with a penniless water ski instructor (Will Hutchins) to learn about life from the bottom up. Suddenly short on money but long on determination, he repairs a radically designed powerboat in order to win the regtta and the affection of a girl who's determined to marry rich!
