The Broadway cast of Eugene O’Neill’s “A Long Day’s Journey Into Night” – including Vanessa Redgrave and Brian Dennehy – take a field trip to Connecticut to visit the playwright’s childhood home. “It’s nice for me to have certain things here in my head. It just gives me a visceral sense of what things mean. Like when [the character of the younger son, Edmund, says], `I don’t want to go upstairs until she’s gone to bed,’ suddenly means something else when you’ve seen how oppressive the ceilings are. Suddenly you have a mental picture for what it means to these boys to go upstairs. Of course, I’d stay up until 4 in the morning drinking if it meant avoiding going up there.”
