Disney's "High School Musical" phenomenon leaps onto the big screen in "High School Musical 3: Senior Year," in which America's favorite high school students (Zac Efron, Vanessa Hudgens, Ashley Tisdale, Lucas Grabeel, Corbin Blue and Monique Coleman) hit senior year. Amidst a basketball championship, prom and a 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 (Matt Prokop, Justin Martin, Jemma McKenzie-Brown) joins in the fun as the film's incredible new music and exciting dance numbers take maximum advantage of the big screen.
