Jimmy Fallon attended the opening day of the The Inheritance on Broadway, and Matthew Lopez found him in tears after the curtain fell, the playwright said on The Tonight Show. Lopez appeared on the talk show with Olivier-winning star Kyle Soller on January 10 and talked with Fallon about finding inspiration in E.M. Forster's Howards End, the novel on which Lopez's two-part generational study of gay life and legacy in America is based, and talked with Soller about making audiences laugh amid The Inheritance's frequent heartbreaking moments. "I've never ever been part of something that breaks the boundary between audiences and performers like this play does," Soller added, excusing Fallon's tearful response. "We can hear the audience reactions, and they're very vocal throughout the performance. They're laughing. They're gasping, and they're weaping openly." Watch the rest of Lopez and Soller's late-night appearance below.
