The Disney Channel is reviving High School Musical.
The channel said Tuesday it's starting a nationwide casting search for the latest sequel in the hit TV movie franchise.
High School Musical 4 will introduce new East High Wildcats and their cross-town rivals, the West High Knights, the channel said.
The cast of the original 2006 movie included Zac Efron, Vanessa Hudgens, Ashley Tisdale and Corbin Bleu. Much of the cast reunited recently for a 10th anniversary tribute to the initial TV movie.
The sequel comes amid network television's fixation on musicals, with projects ranging from NBC's The Sound of Music to Fox's recent hit Grease, which starred Hudgens.
The Disney Channel said details about upcoming open casting calls will be available online soon at www.disneychannel.com/opencall .
An air date for High School Musical 4 was not announced.
