Disney’s “High School Musical” phenomenon leaps onto the big screen in HIGH SCHOOL MUSICAL 3: SENIOR YEAR, in which America’s favourite high school students (ZAC EFRON, VANESSA HUDGENS, ASHLEY TISDALE, LUCAS GRABEEL, CORBIN BLEU and MONIQUE COLEMAN) hit senior year.  Amidst a basketball championship, prom and a big spring musical featuring all of the Wildcats, Troy and Gabriella vow to make every moment last as their lifelong college dreams put the future of their relationship in question.  A crew of sophomore Wildcats joins in the fun as the film’s incredible new music and exciting dance numbers take maximum advantage of the big screen.
