High School Musical 4 Already?

“We are writing High School Musical 4.” This is what Disney Channel Worldwide President Rich Ross told the Hollywood Reporter Tuesday. Although they have yet to start filming High School Musical 3, Disney is already in the works to put out HSM4. Ross did tell Hollywood Reporter that he doesn’t think all the original cast members will be back, but they’ll be introducing new characters in HSM3. Vanessa Hudgens already said that HSM3 would be her last, as did Ashley Tisdale. I’m going to assume Zac is also not returning in the fourth installment. Who knows, though. For the right price, we might see the same cast in HSM4. In the meantime, filming for HSM3 will begin later on this month in Utah.
