This was certainly an iconic film for me. When I saw it at age 12, I doubt my mother knew it was not just another beach movie. And I am not sure with my sketchy ideas of sex, if I picked up on all of it too.
Four college co-eds (Hart, Prentiss, Mimieux and Francis) hit Fort Lauderdale with very different ideas about what they hope to find. One girl thinks she wants to find a sexual partner, one knows she does not, one is hoping to have a passel of babies, the other sings.
This movie manages to be frank in its depiction of 20 years olds in 1960, but idealistic too. It's not a great movie in terms of acting, directing, etc. But it captured the time pretty well--when we were very ambivalent about both feminism and sex. When youth gave little thought to whether they'd have jobs after graduation and instead concentrated on finding partners. Fun music too. You can find more movies at Todd Mason's blog.
