S#@t! Disney's making High School Musical 4!?

It's bad enough that the Execs. from Disney are cranking out a full-length movie version of the wildly popular High School Musical movie franchise due out this year, but just when we all thought that this generation's version of Grease might have finally ended with the story's graduation of the main characters Troy (Zac Effron), Gabriella (Vanessa Hudgens), Sharpay (Ashley Tisdale), Ryan (Lucas Grabeel), Chad (Corben Bleu), and Taylor (Monique Coleman), the corporate pimps at Disney are putting out a fourth sequel. I swear this tired, annoying franchise is becoming the equivalent of having herpes, with one big difference. You can actually deal with herpes.

Even before "High School Musical 3" hits movie theaters in the fall, Disney Channel is starting work on "High School Musical 4."

"We are writing 'High School Musical 4,' " Disney Channel Worldwide president Rich Ross said Tuesday after a presentation at a midtown Manhattan recording studio. It's likely to be a TV movie unlike "High School Musical 3: Senior Year," though that could change. Filming begins in two weeks in Utah.

There's no word on whether the cast and behind-the-scenes talent will gather again for "HSM4," though some characters introduced in the third go-round likely will star in the fourth.

"Are we going to have all the cast back? Probably not," Ross said. "Will we have some of them? I hope so."

What's the point in making another HSM movie if most of the stars of the movie won't even sign up again?

Disney should have learned it's lesson from the Pirates of the Caribbean sequels they trotted out: there can be too much of a good thing. Make number three, then stop. Because this will get tiresome and irritating (as if it already isn't irritating enough).
