Peter O'Shaughnessy developed considerably. In September 1957, he staged the first Australian production of Samuel Beckett's "Waiting for Godot" at the Arrow Theatre in Melbourne with himself as Vladimir and Humphries as Estragon. It proved a hit with both audiences and critics. The critic of the Melbourne "Sun" wrote "so engrossing and well-done is this extraordinary adventure by Samuel Beckett regimented by Peter O'Shaughnessy's tender care that for me the evening passed by on wings". Later in the same year, O'Shaughnessy planned a production of George Bernard Shaw's "Pygmalion" for December, in tandem with a children's play to be performed at matinees.
Samuel Beckett widely discussed and highly prized of 20th-century authors, inspiring a critical industry to rival that which has sprung up around James Joyce. He has divided critical opinion.

Since Beckett's death, all rights for performance of his plays are handled by the Beckett estate, currently managed by Edward Beckett (the author's nephew). The estate has a controversial reputation for maintaining firm control
