Oscilloscope Laboratories is releasing Hal (DVD: $34.99, Blu-ray: $39.99) on April 2. Although Hal Ashby directed a remarkable string of widely admired classics throughout the 1970s, including Harold and Maude, The Last Detail, and Shampoo, he is often overlooked amid the crowd of luminaries from his generation. Director Amy Scott’s exuberant portrait combines rare archival materials, interviews, personal letters, and audio recordings to reveal a passionate, obsessive artist. Ashby was a Hollywood director who constantly clashed with Hollywood, but also a unique soul with an unprecedented insight into the human condition and an unmatched capacity for good, making films that carried an elusive blend of honesty, irreverence, humor, and humanity. Bonus features include audio commentary by Scott and producers Christine Beebe, Brian Morrow, Jonathan Lynch, and Lisa Janssen, as well as segments from “The Cutting Room Floor,” and a behind-the-scenes reel.
