High School Musical 3 Script Finished

The script for High School Musical 3 is completed and a tentative release date of October 2008 has been rumored!

“Fortunately, Peter was able to get [the new script] into us before the strike,” director Kenny Ortega told TV Guide at Sunday’s Diversity Awards. “Now we’re developing our music. It’s exciting. We’re looking forward to beginning in ‘08,” with an eye on an October theatrical release.

Despite much chatter about whom from the original cast has signed on to return — Ashley Tisdale, for one, tells us she definitley has — Ortega maintains, “They’re all coming back.”

The movie won’t be haunted (thank goodness! I thought that was a lame premise) but it will be headed for the big screen! Rumor has it that this last High School Musical movie will focus more on the senior year:

“I would love to do a senior version of ‘High School Musical,’” Zac Efron agreed, admitting that he likes it a lot more than the original idea of ghosts invading East High. “I think ending the series as a theatrical film would be amazing.”
