Courtney Abbott and Chris Sanders, improvisational actors with Catharsis Productions, played out a scenario for Marines and sailors during “Sex Signals” at the Marine Corps Base Hawaii movie theater April 25. “Sex Signals” is an improv-based play with male and female actors who act out different scenes and interacted with the audience. The crowd got involved by providing settings, pick-up lines and asking and answering questions about when a person in a scene might be “going too far.”
