Elvis goes to Florida to water ski and compete in a boat race
The rich son (Presley) of an oil tycoon (James Gregory) takes off to Florida. On a lark, he trades places with an amusing man of low status (Will Hutchins) to see if he can find a woman who loves him just for himself rather than for his wealth. Shelley Fabares plays his love interest, Bill Bixby his rival and Gary Merrill a boat entrepreneur.
Clambake (1967) was Elvis 25th movie and he would only do six more before leaving cinema for good. After the release of this film he only had 10 more years to live.
Its a fun flick and shows that not all of his late 60s movies sucked. While its not on the level of Blue Hawaii (1961), "Kid Galahad" (1962), Roustabout (1964) ...
