Jonathan Groff, who is gay, was closeted when he was cast. In the doc, he confesses he was worried his acting would reveal that he wasn't straight. He says, "The first thing I felt was, 'They're going to know I'm gay. F*ck. I never had sex with a girl, I'm in the closet. I'm just going to pretend that I know what I'm doing.'"
Groff explains that he was scared that being out would ruin his career as an actor. He says, "I was afraid if people knew who I was, they wouldn't find what I was doing believable."
