Shadow Play, described by the author as "a musical fantasy", is a one-act play by Noël Coward, one of ten that make up Tonight at 8.30, a cycle written to be performed across three evenings. Short plays were unfashionable in the 1920s and 30s, but Coward was fond of the genre and conceived the idea of a set of brief pieces to be played across several evenings. The actress most closely associated with him was Gertrude Lawrence, and he wrote the ten plays as vehicles for them both.
