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 agent and sent the manuscript to multiple producers until they met Roger Blin, the soon-to-be director of the play Blin's knowledge of French theatre and vision alongside Beckett knowing what he wanted the play to represent contributed greatly to its success. In a much-quoted article, the critic Vivian Mercier wrote that Beckett "has achieved a theoretical impossibility—a play in which nothing happens, that yet keeps audiences glued to their seats. What's more, since the second act is a subtly different reprise of the first, he has written a play in which nothing happens, twice." The play was published in 1952
