Psych-Out (1968; Richard Rush)

American Bandstand guru Dick Clark did not dig flower power. When "In-a-Gadda-Da-Vida" was a thing, he still was into Bobby Darin. During his short tenure as a film producer at American-International Pictures, he intended a film to show the decrepit existence of hippies for what it really was. Despite how much he may have succeeded in Psych-Out, this remains a key film for those who are nostalgic for the flower power era. Today, this film seems naive, but honestly so was much of the era, but it probably captures the “Summer Of Love” better than any other narrative film.

The Trip (1967; Roger Corman)

Would you drop acid with Bruce Dern?

Before Peter Fonda made the trailblazing Easy Rider with his co-star Dennis Hopper, he was already a counterculture icon from The Trip, in the role of Paul Grove, a TV commercial director on the verge of a divorce from Sally (Susan Strasberg) who falls in with some Hollywood hippy-dippy types, and eventually goes on his first cosmic journey of LSD at Bruce Dern’s pad (see above).  The rest of the film is that long day’s journey through a burning brain where reality and illusion jam on a merry-go-round.  It’s Blowup for the Monkees generation, it’s Chappaqua filmed as a cartoon.
