High School Musical 4 Is in the Works

A new High School Musical movie is in the works, but fans shouldn't expect to see Zac Efron, Corbin Bleu and Vanessa Hudgens singing and dancing on the big screen.

High School Musical 4 will bring the franchise back to television, and it's set to debut as a Disney Channel original movie in 2010 with a new cast of characters.

In crafting this next iteration, we've challenged the entire creative team to raise the bar again — and create something truly worthy of this extraordinary global phenomenon," Gary Marsh, president of Disney Channels Worldwide, said in a statement.

The screenwriter of the next installment, Peter Barsocchini, wrote each of the first three movies in the franchise.
