The original High School Musical cast is not returning for their fourth film. High School Musical 3 is going to be their last since they'll be graduating. And everyone knows that once a show goes to college, it doesn't do as well (not counting 90210). Zac Efron said, "This is probably going to be the last one for a lot of the cast...It's graduation, a lot of us have to move on."

Not to worry though, the franchise will live and there will be a High School Musical 4, but I just don't know if I'll watch it. It's like when they tried to bring in a new class on Saved By The Bell, it just didn't work for me.
