On March 9, 2010, Warner Bros. will release on DVD, The Brothers Warner, a film by Cass Warner Sperling, granddaughter of Harry Warner.

Synopsis: Of the major studios, one was family. Harry, Albert, Sam, Jack – the Warner brothers – turned a storefront that used a sheet for a screen into a dream factory rooted in the credo of educate, entertain and enlighten. In this fascinating documentary, filmmaker (and Harry’s granddaughter) Cass Warner Sperling tells a story of sibling rivalry, social conscience and the silver screen. It’s a story of pioneering (risking all for Talkies) and politics (standing alone in Hollywood against the Nazis), of reels (The Public Enemy, Casablanca and more) and rifts (including a shocking family betrayal). It’s a story told from the inside (via rare family archives) by those who lived it (among them such stars as Dennis Hopper, Debbie Reynolds, Tab Hunter and more) and from the outside by film historians. The people, the pictures, the tales untold on camera until now – The Brothers Warner educates, enlightens, entertains, reveals.
