High School Musical

High School Musical is a 2006 American teen/romantic comedy musical television film and the first installment in the High School Musical trilogy. Upon its release on January 20, 2006, it became the most successful film that Disney Channel Original Movie (DCOM) ever produced, with a television sequel High School Musical 2 released in 2007 and the feature film High School Musical 3: Senior Year released theatrically in October 2008. It is the first (and, as of 2016, the only) DCOM to have a theatrical sequel. The film's soundtrack was the best-selling album in the United States for 2006. On January 20, 2016, Disney Channel showed a rebroadcast of the first movie for its 10th anniversary, with the original cast (excluding Zac Efron) returning for the event.
