Woodstock is a 1970 American documentary on the Woodstock Festival that took place in August 1969 at Bethel in New York. Entertainment Weekly called this film the benchmark of concert movies and one of the most entertaining documentaries ever made. The film was directed by Michael Wadleigh and was edited by (amongst others) Martin Scorsese and Thelma Schoonmaker; Schoonmaker was nominated for an Academy Award for Film Editing.
Woodstock was a massive commercial and critical success. It received the Academy Award for Best Documentary Feature, as well as a nomination for Best Sound (Dan Wallin, L. A. Johnson). The film was also screened at the 1970 Cannes Film Festival, but wasn't entered into the main competition. The Official Director's Cut, spanning 225 minutes, was released in 1994.
