Disney has begun work on a fourth installment of the High School Musical film series, with the movie’s main stars Zac Efron, Vanessa Anne Hudgens not willing to appear.
High School Musical 3: Senior Year is set for release later this year and fans were led to believe the movie would be the final episode in the hit franchise.
But now the company has revealed plans are well underway for another film, with a script already being penned.
Disney Channel Worldwide President Rich Ross confirmed the news to MTV, saying: "We are writing High School Musical 4.
"We have learned that just putting a number next to a title is a very old idea. We have to have a new story."
All the stars of the original TV movie, including Zac Efron who plays Troy, Vanessa Hudgens starring as Gabriella and Ashley Tisdale in Sharpay’s role, have signed up for the third picture.
However Ross fears Disney might not be able to persuade the entire original cast to reprise their roles for a fourth time.
He adds, "Are we going to have all the cast back? Probably not. Will we have some of them? I hope so." But Zac Efron and Vanessa Hudgens will pass on the 4th installment of the Disney Channel Franchise.
Auditions and Casting information for High School Musical 4 will be posted Here.
