Wildcats unite! The original cast of "High School Musical" will reunite for the Disney Channel Original Movie's 10th anniversary.

Vanessa Hudgens, Ashley Tisdale, Corbin Bleu, Lucas Grabeel and Monique Coleman gathered at a suburban Los Angeles high school to reminisce about the film's global success. Segments from their discussion will air during a special telecast of the movie on Wednesday, Jan. 20 at 8 p.m. EST on Disney Channel.

Missing cast member Zac Efron pre-taped a message for "High School Musical" fans that will also air during the special.

"Seeing the cast of 'High School Musical' back together again reaffirms what made it special 10 years ago. It's their optimism, their dedication and their extraordinary talent - as a group - that made this such an exceptional movie and cultural phenomenon," Gary Marsh, president and chief creative officer of Disney Channels Worldwide, said in a statement. "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."

"High School Musical" premiered on Jan. 20, 2006 and was watched by 7.7 million viewers in the U.S. - the highest ratings for any telecast ever on Disney Channel at the time. The soundtrack also reached No. 1 on the Billboard Top 200, the first-ever TV movie soundtrack to accomplish the feat.
