Otherwise Engaged is a bleakly comic play by English playwright Simon Gray. The play previewed at the Oxford Playhouse and the Richmond Theatre, and then opened at the Queen's Theatre in London on 10 July 1975, with Alan Bates as the star and Harold Pinter as director, produced by Michael Codron. Ian Charleson co-starred as Dave, a Glasgow lout. Michael Gambon took over from Bates in 1976, "playing it for a year, eight times a week." The play also had a successful run on Broadway, opening in February 1977 with Tom Courtenay as Simon and Carolyn Lagerfelt as Beth. It won the New York Drama Critics' Circle Award for Best Play.
