With all the reminiscing about the Woodstock 50th, I couldn't let Peter Fonda's passing go unmentioned. His Easy Rider was just as much a cultural icon as the 3 Days of Peace and Music.
When he and Dennis Hopper came up with the idea of Motorcycle-Cowboys looking for America (or the Mardi Gras, or for whatever) they created a touchstone of the times. He found a place located somewhere between Roger Corman and John Ford, and claimed it.
Screenwriter Terry Southern turned their rough outline into a working Script. Even though a large portion of the dialogue in the movie is improvised ( Venusians ? The Man is at the Window ?? ), the screenplay was Oscar nominated. Jack Nicholson even suggested some songs for the Soundtrack. They talked some studio into a $350K bankroll, and rode off into the desert to invent a new movie genre.
Great line from the movie --"Share this when you're with the right people."
