This movie is gay!
And I mean that it the most beautiful sense! Come on, all those hot young men, showing their buff (for that era) bodies and living on the beach together. (Key West, anyone?) They sing. They are all as hot as hell and want nothing to do with a pretty blond gal. Not too much of a stretch.
I definitely think there was some action goin' on. If the cabana's was a'rockin, I wouldn't have come a'knockin'.
Ironically, I read that Cliff Robertson was a big stinkin' homophobe. He reportedly refused the lead in a TV movie (That Certain Summer) because it had a gay theme, stating he'd "rather play Hitler."
The Nimble, Limber One.
