The New "High School Musical"

After the success of the Disney Channel's movie, "High School Musical," why wouldn't producers want to make another? Now tweens across the country are preparing themselves for "High School Musical 2," set to premiere Aug. 17.

The first movie is the story of Troy, a jock played by superstar Zac Efron, and Gabriella, a brainiac played by Vanessa Anne Hudgens. They audition for the high school musical and throw their fellow students into a frenzy.

Since its debut the film has been seen by 170 million people worldwide, winning two Emmy awards along the way. The soundtrack has sold more than 7 million copies in the United States and it was the No. 1 best-selling album of 2006. It is in Guinness Book of World Records for having nine singles on the billboard top 100 chart. The DVD has sold close to 8 million copies.

The film also launched the young cast to stardom. Hudgens released a top-selling solo album, as did Ashley Tisdale. Monique Coleman became a fan favorite on "Dancing with the Stars" and Efron had a leading role in the big screen musical "Hairspray."

"High School Musical 2" will move the action from school halls to summer vacation. But it was literally yesterday that Coleman said she realized how huge the "High School Musical" phenomenon has become.

"I mean, it's something that every single thing we've done is just like, one thing tops the next," she told Saturday Early Show co-anchor Maggie Rodriguez. "I think it started with being in New York City and being able to perform in Times Square. From that moment on it kept getting bigger and bigger and better and better. And it's incredible."

Tisdale said the movie is so popular because it's almost like a "Grease" for this generation of kids.

"We haven't had that in a long time," she said. "It could be a combination of things. It's the fans that made is so huge, the kids, we're grateful for them."

Hudgens said in the next installment of the "High School Musical" phenomenon, the plot intensified.

"We stepped it up a notch, more dancing, more songs and there's definitely a lot more drama," she said. "It's crazy. Some parts of it, there's like a love square. It gets really complicated."

Now this group of young performers has made two movies together and has done a concert tour. They have formed a very tight bond.

"Being on the road with these guys is so much fun, being able to share that experience on the stage where you hear the audience applauding and you just feel the energy. It's amazing," Hudgens said. "I mean, like, shooting the movie together, we're together every single day. I mean, we're really a big family. We get closer and closer."

Rodriguez asked each cast member a personal question. Here are the questions and responses.

Zac Efron:

"Zac, what do you sing in the shower?"

"Oh, man, anything," Efron said. "Probably the last song I heard. It changes every day."

"Do you have a music idol?"

"A music idol? No, I'm constantly listening to all genres. Not really. I love, like ... Justin Timberlake. Not that I sing his songs in the shower. Don't worry."

Monique Coleman:

"Monique, what do you do for fun?"

"I sing. I was scared like, 'What's mine going to be?' I hang out with friends. I'm a low-key person. I like to spa … Getting my nails done, talking with friends, watching movies. Just doing really quiet nights."

Ashley Tisdale:

"Ashley, what would you be doing if you couldn't sing and act, which we can't even imagine?"

"Seriously, I love what I do but I'm very creative person. I like to write, so maybe, you know — obviously I wrote three songs on my album I co-wrote so probably something with writing. Maybe writing scripts. I love it."

Vanessa Anne Hudgens:

"Lastly, Vanessa, do you have or did you have posters of anybody in your room growing up?"

"This is the most random thing ever, but I had an animation poster of Peter Pan when he was flying. That's all."
