Yup. 1967 was a HUGE year in film... There was The Graduate which had sex/nudity, Bonnie and Clyde which had graphic violence, and Guess Who's Coming To Dinner, which was the first major motion picture to have a black/white sexual relationship and show the racial tensions surrounding it.
The Graduate is about Ben, this kid who just gradutated college and comes how to his rich family. Mrs. Robinson is a family friend and take Ben to her house, gets naked, and tells him she's "aviable." Next thing you know, Ben's got a relationship going on with her and her daughter Elaine. LOL, anyway, great movie. Check it out. Check out all three of those movies.
