All cast members do their own singing and dancing.
Artie is named for Brad Falchuk's friend Arthur Stroyman, who was a jock who never understood the artsy kids in school.
70 songs were used in the first thirteen episodes.
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).
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.
The role of Principal Figgins was originally written for a white actor. They ended up casting Iqbal Theba who was born in Karachi, Pakistan.
Cory Monteith didn't sing in his first audition video. He instead produced a beat using makeshift drums. The producers liked his personality and originality so much they called his agent and requested he fly to Los Angeles for a live audition.
On the day of her audition, Lea Michele was in a car accident right outside of the studio. She came in literally still pulling glass from her hair.
The role of Quinn Fabray was not cast until the night before filming began.
Several times during filming they had to stop rolling to tell Kevin McHale to stop tapping his feet to the beat of the music.
Much like her character Emma Pillsbury, Jayma Mays has a peanut butter and jelly sandwich every day.
Terri works at Sheets N' Things which is obviously a play on Linens N' Things. By the time the Pilot aired Linens N' Things had closed all of its stores across the country.
Much of the main cast of Glee performed for President Barack Obama, his family, and the approximately 30,000 children and parents in attendance at the 2010 White House Easter Egg Roll on April 5, 2010. Among the songs the Glee group sang were "Don't Stop Believin'," "Over the Rainbow," and "Sweet Caroline," which songwriter Neil Diamond has said was originally written as a tribute to Caroline Kennedy, the daughter of President John F. Kennedy; Malia Obama and Sasha Obama, the daughters of President Obama, were in the front row to hear the concert.
Iqbal Theba (Principal Figgins) does not like wearing make up. The make up crew lightly powders him with anti-shine right before the cameras roll.
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.
Lea Michele (b. 1986) is 8 years older than her character, Rachel Berry (b. 1994).
The restaurant the characters frequent is called "Breadsticks". The show creator, Ryan Murphy, previously made a high-school themed show called "Popular" which featured the students congregating at a restaurant called "Croutons".
Original Audition Songs: Matthew Morrison sang and played 'Somewhere Over the Rainbow' on the ukulele. Lea Michele sang 'On My Own' from 'Les Miserables.' Chris Colfer sang 'Mr. Cellophane' from 'Chicago.' Jenna Ushkowitz sang 'Waiting for Life to Begin' from 'Once on this Island.' Kevin McHale sang The Beatles. Amber Riley originally sang a pop song for her audition, but the producers asked her to sing 'And I Am Telling You' from 'Dreamgirls.' Jayma Mays sang 'Touch-a Touch-a Touch Me' from _The Rocky Horror Picture Show_. Although many people believe Cory Monteith sang 'Can't Fight This Feeling' for his audition, but he really sang 'Honesty' by Billy Joel, which he revealed on the Canadian radio show Q. By the end of the first season, Morrison, Michele, Colfer, and Riley had performed their songs on the actual show. Mays sang hers in the second season.
Fans of the show refer to themselves as "Gleeks". The show embraced this and season two billboards and bus ads encouraged fans to "Gleek Out".
Most of the cast were unknown faces, which is exactly what the the producers wanted. And such was the level of spontaneity, auditions were often populated by youths who literally walked in off the street, eager for a crack at stardom.
SPOILER: 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.
In 2010, Ryan Murphy announced that "Glee" would be providing the funding for a job readiness counselor position at New York City's Hetrick-Martin Institute, an agency that provides support services and counseling to LGBTQ youth and that also runs the Harvey Milk High School, a New York City public school for LGBTQ teens who have been bullied in their previous schools. The job had been eliminated because of budget cuts at the institute. Murphy also announced that the show will provide $25,000 in matching scholarship funds for Harvey Milk High School.

In early drafts of the pilot script, Quinn's name was "Liz Fabray".
