Trumbo, director Peter Askins' new documentary about the life and work of blacklisted screenwriter Dalton Trumbo, began life as a series of letters archived by Dalton Trumbo's son Christopher; it then became a two-person play. On-screen -- where it's become one of the breakout documentary surprises of this year's Toronto International Film Festival -- the story mixes archival footage and interviews with brand-new readings of Trumbo's letters by a cast of true talents -- Paul Giamatti, Joan Allen, Donald Sutherland, Michael Douglas, Josh Lucas, Liam Neeson, Nathan Lane, David Strathairn, Brian Dennehy and Donald Sutherland. Trumbo isn't just a misty look back at a long-past Hollywood -- the issues of free speech it raises are relevant today, as demonstrated at the public screening where an audience member asked if, in light of the actions of Stalin's Russia, the House Un-American Activities Committee was perhaps justified in their attack on 'The Hollywood Ten.' ... Cinematical spoke with Askin in Toronto about the transition between stage and screen, finding his film's impressive cast, his thoughts on the blacklist and much more.
