Most anyone familiar with O'Neill will have heard that his work was highly personal. In this illuminating and arresting documentary, director Ric Burns shows us just how personal, focusing on the striking parallels between the writer's anguished life and work. O'Neill's ability to expiate his own inner demons through his art came at a terrible cost. Though he achieved fame and renown, he could not enjoy it; indeed, his tortured creative process drove him to drink and a premature death. However, as evocative readings by Al Pacino, Vanessa Redgrave and Jason Robards make abundantly evident, he left behind quite a legacy.
