Carrie Coon in Broadway's 'Bug' Matthew Murphy Carrie Coon, the star of Broadway‘s Bug and wife of the thriller-play’s author, has revealed exactly what prompted the cancellations of two shows last week just before opening night: She had some sort of onstage allergic reaction to the fake stage blood used throughout the more violent scenes of the play. Appearing on Late Night With Seth Meyers last night, Coon told the talk host that the trouble started during the Wednesday, January 7, matinee performance during a scene in which Coon sprays fake blood up her nose to simulate a nose bleed from a violent encounter.
