Agron said in a 2009 interview pertaining to her casting session: “I nearly bailed on my audition for the show. I was so nervous.” Before being cast as Quinn, the show’s producers wondered if she appeared too innocent. Agron said in an interview: “They told me to come back with straight hair and to dress sexier. Later that week, I started work.” She auditioned with Frank Sinatra’s “Fly Me to the Moon”. Quinn is described by Agron as Rachel Berry’s (Lea Michele) enemy, and “terrible, the meanest girl.”The character was originally conceived as the antagonistic queen bee head cheerleader, a departure from Agron’s actual high school experience.
