In the 1950s, Gielgud was involved in directing a run of Sherlock Holmes radio plays starring his brother John as the lead character, with Ralph Richardson as Dr Watson and Gielgud himself once appearing as Mycroft Holmes. These were broadcast on the BBC's Light Programme. By this time Gielgud was in conflict with junior colleagues in the drama department; unlike them he was unable to appreciate the work of playwrights such as Harold Pinter and Samuel Beckett. Beckett's "Waiting for Godot" would have made its English début in a radio production had Gielgud not rejected it.
