Ashley Tisdale and her "High School Musical" co-stars recently reunited for the film's 10th anniversary.

The 30-year-old actress and cast mates Vanessa Hudgens, Monique Coleman, Corbin Bleu and Lucas Grabeel celebrated the milestone sans Zac Efron on a special episode of "Good Morning America" scheduled to air Wed., Jan. 20.

"It was such a whirlwind. It felt like we were kinda swept up into this vacuum," Hudgens said of the Disney Channel movie's success. "At one point it literally felt like we were the Beatles."

"It's amazing. For me, I kind of embrace the 'I want it all' of [my character] Sharpay," Tisdale added. "And I'm doing it all. Got a clothing line, a makeup line coming out, [I'm] producing [and have] a movie coming out in May. It's been insane."

"High School Musical" premiered to 7.7 million viewers in 2006, and released the best-selling soundtrack of the year. The film was followed by the TV sequel "High School Musical 2" in 2007, and the theatrical sequel "High School Musical 3: Senior Year" in 2008.

"It's their optimism, their dedication and their extraordinary talent -- as a group -- that made this such an exceptional movie and cultural phenomenon," Disney Channels Worldwide president Gary Marsh said in a press release.

"Ten years later, the movie continues to delight audiences around the globe, not just for its memorable song and dance numbers, but for its universal themes that continue to resonate with fans everywhere -- express yourself, believe in yourself and always follow your dreams."

The cast also filmed segments to air during Disney Channel's telecast of "High School Musical" at 8 p.m. ET on Wednesday. The co-stars will appear again on a Radio Disney Insider interview Thurs., Jan. 21 on the Disney Channel and the Radio Disney app.
