Glee

The role of Quinn Fabray was not cast until the night before filming began.

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.
