Women were 100x more attractive back then. Natural everything, no trashy tattoos, not a tacklebox worth metal hooks everywhere, and no garish hair dye.
I have seen this before and still enjoy it. What the commentator in the film says is very well researched and true. Of course, for this film to appeal to most people, they had to only use good looking and physically fit people in the film. From the looks of the areas usually covered by swimwear, it looks like some of the actors hadn't spent a lot of time nude in the Sun (chuckle). I really appreciated seeing people who hadn't removed their pubic hair. This was an older film, but very relevant to our attitudes today.
