Audiences aren’t alone in being pleasantly confused by Sam Shepard’s 1978 Pulitzer Prize winner Buried Child - the company behind the National’s current revival are equally mystified. At the post-show discussion as part of last night’s Outing, actor M Emmet Walsh, who plays patriarch Dodge, admitted: “I thought I understood the play when I came here, but I soon realised I was wrong.” Fellow American Lauren Ambrose – who, like Walsh and co-star Elizabeth Franz, is making her London stage debut in the tragi-comedy – added that, though she still didn’t fully understand everything, “Every night it reveals something new.” On the subject of Buried Child’s many unanswered questions, director Matthew Warchus commented: “One of the great things about the play is that it manifests things that are difficult to put into words. In rehearsals, you have to make a choice about which questions are productive to answer and which are not. It’s not productive to work out who planted all the vegetables it’s just important to enjoy the fact that they’re there. You need to try to hone in on the best detonation that would be caused by answering a question. If you limit yourself by answering a question, don’t answer it.”
