"High School Musical 3" reunites the original cast, who skyrocketed to teen stardom when the original film premiered in 2006 on the Disney Channel, breaking records for viewership and recording sales. The third film is the first of the "HSM" series to debut in movie theatres.

Original "HSM" director and choreographer Kenny Ortega again leads original stars Zac Efron (Troy), Vanessa Hudgens (Gabriella), Ashley Tisdale (Sharpay), Lucas Grabeel (Ryan), Corbin Bleu (Chad) and Monique Coleman (Taylor), through the high-energy film.
