"In 1967, two movies, Bonnie and Clyde and The Graduate sent tremors through the industry. Before anyone realised it, there was a movement - instantly dubbed the New Hollywood by the press - led by a new generation of directors." (Easy Riders Raging Bulls - Peter Biskind.)

Bonnie and Clyde - "Disregard for time-honored pieties of plot, chronology, and motivation; a promiscuous jumbling together of comedy and tragedy; ditto heroes and villains; sexual boldness; and a new, ironic distance that withholds obvious moral judgements." 

(Stefan Kanfar on the characteristics of the New Cinema, from the book "Easy Rider Raging Bulls" by Peter Biskind.)

"Warners released the movie in 340 theatres. In September, it had grossed $2600 for a week at one theatre in Cleveland; it played the same theatre in February and grossed $26000."" Still, the numbers were dramatic. By the end of 1967, the picture had netted $2.5 million in rentals. In 1968, when it was re-released, it netted $16.5 million in rentals, the making it one of the top 20 grossing pictures of all time"
