Jack Nicholson's directorial debut. It was one of two post-"Easy Rider" Nicholson films that had yet to be released on video of any kind - the other being A Safe Place (1971) - until 2010 when the Criterion Collection released both films on DVD and Blu-Ray as part of their "America Lost And Found - The BBS Story" box set.
The outdoor riot scene was shot during an actual campus protest. During filming, students at a nearby college got in a scuffle with police. When director Jack Nicholson heard about it, he took his actors and crew to the site of the mêlée and shot footage without permission.
