Lee, Nolan on Ledger

Two of the directors that worked with him pay tribute to the late Heath Ledger:

Ang Lee, Academy Award-winning director of Brokeback Mountain: "He brought to the role of Ennis more than any of us could have imagined -- a thirst for life, for love, and for truth, and a vulnerability that made everyone who knew him love him. His death is heartbreaking."

Christopher Nolan, director of Ledger's final completed performance in The Dark Knight, currently being edited: "Heath was bursting with creativity. It was in his every gesture ... I see him every day in my edit suite. I study his face, his voice. And I miss him terribly."
