High School Musical centers on the unlikely friendship that evolves between the jock Troy and brainiac Gabriella at a karaoke contest. Little did the two know that she would be transferring into his school. The duo decide — against their friends' wishes and to the dismay of school stars (a drama queen and her twin brother) — to audition for the high school musical.

The cast features Zac Efron ("Summerland"), Vanessa Anne Hudgens, Ashley Tisdale ("The Suite Life of Zack and Cody"), Corbin Bleu, Lucas Grabeel, Monique Coleman as the featured teens with Alyson Reed, Bart Johnson and Joey Miyashima.

Ortega directed and choreographed Disney's "Newsies."
