In her audition for the role, Lea Michele sang "On My Own" from Les Miserables. However, the pianist cut the second verse without telling her. She stopped singing and told him "We have to go back and do the verse!" The writers laughed, and later said she definitely had the Rachel role down.

She won an Emmy for her work on the show.

The original idea of Glee was inspired by Ian Brennan's own experience as a member of Prospect High School's show choir. It was supposed to be a film, instead of a television series. Brennan wrote the first draft in August 2005, and completed it in the same year. The script, however, did not receive any interest from producers at that time. Michael Novick, a friend of Brennan's and a television producer, later gave Ryan Murphy a copy of Brennan's script, as they are members of the same gym. Murphy himself joined show choir when he was young, and thus related to the script. Murphy and Brad Falchuk suggested that Glee should be produced as a television show. Therefore, the three joined together and re-wrote the script. The re-written script was sent to FOX, and picked up immediately. The three decided to write all of the episodes by themselves. Murphy and Falchuk became Executive Producers and Directors of the show, while Brennan is a co-Executive Producer. Novick also became a Producer of this show.
