Their Big Moment is a 1934 American mystery film directed by James Cruze, from a screenplay by Arthur Caesar and Marion Dix. The film starred ZaSu Pitts and Slim Summerville. It is based on the 1933 West End play Afterwards by Walter C. Hackett which had run for more than two hundred performances in London. While most of the Pitts-Summerville teamings were comedies, this was a serious drama in which they merely played comic-relief characters; their star billing was thus misleading.
