Here is a sampling of the top grossing American films for 1967 and 1968. There is a big shift towards the hippie culture becoming commercialized in 1968.
Films of 1967:
A pulpy film of women and their pills:
The Graduate: An unhappy housewife attempts to seduce a young, indecisive man. Cool Hand Luke: Luke intentionally gets himself arrested by cutting off parking meters. In prison, he refuses to align with the hierarchy enforced by the warden, “the man with no eyes.”
Guess Who’s Coming to Dinner: Joanna returns home to introduce her parents to her new fiance, John Prentice, a black physician. Conversations about society, equality, and racism ensue.
