"Waiting for Godot" extract from wikipedia page

Setting

There is only one scene throughout both acts. Two men are waiting on a country road by a tree. The men are of unspecified origin, though it is clear that they are not English by nationality (and in English-language productions are traditionally played with Irish accents). The script calls for Estragon to sit on a low mound but in practice – as in Beckett's own 1975 German production – this is usually a stone. In the first act the tree is bare. In the second, a few leaves have appeared despite the script specifying that it is the next day. The minimal description calls to mind "the idea of the lieu vague, a location which should not be particularised".^[50]
Alan Schneider once suggested putting the play on in a round – Pozzo has often been commented on as a ringmaster^[51] – but Beckett dissuaded him: "I don't in my ignorance agree with the round and feel Godot needs a very closed box." He even contemplated at one point having a "faint shadow of bars on stage floor" but, in the end, decided against this level of what he called "explicitation".^[52] In his 1975 Schiller-Theatre production there are times when Didi and Gogo appear to bounce off something "like birds trapped in the strands of [an invisible] net", in James Knowlson's description. Didi and Gogo are only trapped because they still cling to the concept that freedom is possible; freedom is a state of mind, so is imprisonment.
