4063. Sharpay Evans

Sharpay Evans is the main antagonist of the High School Musical series and the High School Musical movies, particularly in the first two High School Musical movies. She is not the main antagonist as a character in the movie High School Musical 3: Senior Year. In High School Musical 2, her sisters are called the Sharpettes, one is played by Tanya Chisholm, one is played by Kelli Baker and one is played by McCall Clark. She is played by Ashley Tisdale.

She is the co-president of the East High drama department alongside her fraternal twin, Ryan Evans, with whom she has starred in seventeen school productions. Sharpay appears to have the most power in the drama department, leaving Ryan Evans as her right-hand man. However, the sibling loyalty is not always mutual. Classmate Taylor McKessie suspects that if Sharpay "could figure out how to play both Romeo and Juliet, her own brother would be aced out of a job." Sharpay's family is very affluent; their wealth stems from the country club, Lava Springs, her parents own.
Sharpay Evans is portrayed by Ashley Tisdale in the first three films of the High School Musical series. Ashley Tisdale, who was previously known for her starring role on the Disney Channel series "The Suite Life of Zack and Cody", insists that she was not offered the role of Sharpay and had to audition, also claiming that she almost didn't get the role because the Disney executives did not think she could play the "mean girl" role based on her performance in "The Suite Life". Tisdale said that she went into the auditions at the last minute, but felt very comfortable in front of the Disney executives, as she already knew them. To ensure that viewers loved to hate her character, Tisdale looked to Rachel McAdams' performance in Mean Girls. Although there is room for a possible return of Sharpay in High School Musical 4, Tisdale will be involved in the project.
