At the top of the show, Keanu Reeves’ Estragon and Alex Winter’s Vladimir make a “1990s” reference to their past life together. They make their entrance at the back of the stage, which designer Soutra Gilmour has turned into a gigantic tunnel. Regarding the broken link in this ensemble, what Reeves does have going for him is a look. Of course, there are the Laurel & Hardy black derbies, also worn by Pozzo and Lucky. Over and over again, he sends Reeves and Winter, as well as Dirden, running up the sides of the tunnel only to slide back down.
