Hoffman rehearsed for three weeks with the play's original star, Lee J. Cobb, and remembers seeing his stage performance: "I'll never forget that period in my life. It was so vivid, so intense, watching Lee J. Cobb and his sixteen-inch guns as Willy. God, how I think about what I saw on that stage!" Brenner adds that Hoffman "has been training like a boxer for the role that so exhausted Cobb he had to be replaced after four months." The original play was directed by Elia Kazan, who Hoffman considers "the perfect director, the best there ever was. . . . God, I would have done "anything" to have worked with Kazan."
