Haskell Wexler on Roger Ebert, ‘Days of Heaven’

Haskell Wexler is one of the most influential cinematographers ever - his credits include 'The Conversation', 'In the Heat of the Night', 'The Thomas Crown Affair', 'Bound For Glory' and 'Who's Afraid of Virginia Woolf?' He's in Champaign Illinois this week to introduce the film 'Days of Heaven' at Ebertfest. We spoke with him about his friendship with Roger Ebert, the switch to digital film, and his own beloved subversive 60s movie, 'Medium Cool'.
