We all know the stage musical HAIR, but the film adaptation, directed by Miloš Forman, came out in 1979, well after the demise of the Age of Aquarius, and thus didn't make much of a dent at the box office. The movie deviates greatly from the original stage production, but Forman, despite being born and raised in Czechoslovakia, manages to capture the zeitgeist of the era. No wonder he'd go on to win an Oscar a few years later for AMADEUS.
Pillow Talk (1959), Doris Day, Rock Hudson, Tony Randall, directed by Michael Gordon. A studly bachelor develops a cunning plan to seduce his best friend's girl by pretending to be two people: his nasty self and a nice Texan. Good thing this is a comedy or that would be very bad. Everyone has opulent apartments, clothes and offices. It's kind of a return to the screwball comedies of the 1930s; people wanted to see rich and fashionable settings then, too.
