"High School Musical is part of Disney Channel's DNA. It embodies all that we stand for," says Disney Channel head Gary Marsh. "As a way of continuing to embrace that heritage, we're excited to announce 'the start of something new' — as we launch a search for a new class of East High Wildcats to star in a fourth installment of the High School Musical franchise."

The High School Musical franchise launched the careers of Zac Efron and Vanessa Hudgens over ten years ago. Will it be able to do the same for new talents? More importantly, who from the original cast will return to East High for the new adventure?
