Jenna Fischer from The Office just did an interview with Playboy and told them about a conversation she had when she first moved to LA with playwright/screenwriter Shem Bitterman, who told her she wasn't a real actress.
"I had been living in Los Angeles for about a year and was a member of a theater company. One night, after a play, I went to a party and ran into the playwright. He said, 'What's your story?' I said, 'I'm from St. Louis. I just got here. I want to be an actress.' He said, 'I'm writing a film, and I think you'd be great for it. But I have a question for you - would you ever do a raunchy sex scene in a movie? Like really raunchy, with nudity?' I kind of laughed and said, 'Well, I wouldn't do anything I wouldn't be proud to show my parents.' And he said, 'Well, you're not a real actress, then.' I was stunned.
"He said, 'A real actress would say yes. A real actress would piss herself onstage if that's what it took. Sylvester Stallone did porn. Shelley Winters pissed herself onstage. Every play, every movie I write has nudity in it. You know why? Because that's how I know if I'm working with real actors. You're not a real actress. You should just go home. You don't have what it takes.'
"I went home and cried and cried and cried. What an asshole, I should have told him, 'How about I piss on your face? Does that make me a real actress? Let's try that. I'll do that right here. I'll do that today.' Bring me Shem Bitterman."
