High School Musical is a 2006 American teen/children's romantic comedy musical television film and the first installment in the High School Musical trilogy. With a plot described by the author and numerous critics as a modern adaptation of Romeo & Juliet, High School Musical is a story about two high school juniors from rival cliques – Troy Bolton (Zac Efron), captain of the basketball team, and Gabriella Montez (Vanessa Hudgens), a shy transfer student who excels in mathematics and science. Together, they try out for the lead parts in their high school musical, and as a result, divide the school. Despite other students' attempts to thwart their dreams, Troy and Gabriella resist peer pressure and rivalry, inspiring others along the way not to "stick to the status quo". High school diva Sharpay Evans (Ashley Tisdale) will do anything to sabotage the friendship between Troy and Gabriella and also get a lead in the school musical, assisted by her brother Ryan (Lucas Grabeel).
