Harold Pinter's brilliant early play-on-film, The Birthday Party, is one of his best efforts, and perhaps, with The Homecoming, the pinnacle of the Theater of the Absurd. The plot itself is simple. Two men come to visit Stanley, a classical pianist who has, for unknown reasons, left his home and is staying with a provincial couple. He is visited by Shamus McCann (Patrick McGee) and Nat Goldberg (Sydney Tafler). They alternately celebrate and menace Stanley, who may or may or may not know them. Nothing is clearly stated. Most of the dialogue consists of insinuations and vague threats. Performances across the board are outstanding, with Robert Shaw outdoing himself as Stanley Weber. Moultrie Keisall as Petey is excellent but understated, and his final words really put the cherry on the birthday cake. (sorry for the pun). Nothing I can say can communicate the unique strangeness and power of this film. Top marks, 5 stars, classic.
