Glee

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).

Heather Morris (who had been a back-up dancer for Beyoncé Knowles' tour) was hired to play the character of Brittany after she was first called in by show choreographer Zachary Woodlee to teach the "Single Ladies" dance to the cast.

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.
