• The character of Kurt was written for Chris Colfer after he originally auditioned for the role of Artie. The writers told him that he looked like one of the Von Trapp kids, and Chris told them he actually just starred in The Sound of Music, playing Kurt Von Trapp. This obviously stuck in the writers' mind, as they called his character Kurt Hummel (the surname after the cherubic figurines).

• Several times during filming they had to stop rolling to tell Kevin McHale to stop tapping his feet to the beat of the music.

• The only time Sue calls Emma by her correct name is the Pilot. All other times, she has "mistakenly" called her names like Irma, Alma, Ellen, Arlene, You, or the Redhead.

•Ryan Murphy wrote the part of Rachel Berry with Lea Michele in mind.

• New Directions was originally supposed to win regionals at the end of the first season, as Series Creator Ryan Murphy didn't think the show was going to be picked up for a second season. When he became aware a second season was going to be made he changed the outcome of the season one finale, to make their drive to win in the second season more passionate.
