Trivia, insights & behind the scenes
This was Lucas Grabeel's first Disney project, filmed just months before High School Musical catapulted him to teen idol status. The Sharpay energy was already forming.
The third installment shifted from Oregon locations to Los Angeles soundstages, losing the cozy Pacific Northwest atmosphere that defined the first two films.
