Overview
The Birthday Party is a 1968 British drama neo noir directed by William Friedkin and starring Robert Shaw. It is based on the 1957 play The Birthday Party by Harold Pinter. The screenplay for the film was written by Pinter as well. The film, and the play, are considered examples of "comedy of menace", a genre associated with Pinter.
The film was a passion project for Friedkin, an admirer of the play, and he remained proud of the film after its release, though it was a box office disappointment. It influenced his later work, particularly The Exorcist.
Plot
A man in his late 30s named Stanley is staying at a seaside boarding house, when he is visited by two menacing and mysterious strangers, Goldberg and McCann. Stanley's neighbour, Lulu, brings a parcel containing a boy's toy drum, which his landlady, Meg, presents to Stanley as his "birthday present."
Goldberg and McCann offer to host Stanley's birthday party after Meg tells them that it is Stanley's birthday, although Stanley protests that it is not his birthday. Through the course of the party, the actions of Goldberg and McCann eventually break down Stanley, and they take him away from the house, purportedly to get medical attention (from "Monty") in their car. Meg's husband Petey (who did not attend the party because he was out playing chess) calls after Stanley: "Stan, don't let them tell you what to do". Meg, still somewhat hung over, is unaware that Stanley has been taken away, since Petey has not told her, and she tells him that she was "the belle of the ball."
