To ensure that she and Ryan remain in the spotlight, Sharpay convinces Ms. Darbus, the musical's director, to switch the date of the callbacks to the same day as Troy's district championship basketball game and Gabriella's national decathlon .

Despite having little involvement in the show, the fixed competition's prize, the Star Dazzle Award, was going to be given to her, but she selflessly awards the prize to her brother, who arranged Troy and Gabriella's duet . By the third film, Sharpay's popularity seems to be limited among admiring boys . In her senior year, Sharpay meets Tiara Gold, a British transfer student eager to learn the ropes at East High by becoming Sharpay's student . Tiara's dedication is impressive, but it turns out to be a facade . On opening night of the spring musical, Tiara attempts to upstage Sharpay, but fails .

While in New York, she meets Peyton Leverette, the son of her mom's college friend, who takes her to a new apartment after she got thrown out of a penthouse for refusing to throw her dog out .

Tisdale, who was previously known for her starring role on the Disney Channel series "The Suite Life of Zack & 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 . </P> <Table> <Tr> <Th_colspan="2"> Ryan Evans </Th> </Tr> <Tr> <Th_colspan="2"> High School Musical film series, Sharpay's Fabulous Adventure' character </Th> </Tr> <Tr> <Th> Portrayed by </Th> <Td> Lucas Grabeel </Td> </Tr> <Tr> <Th> First appearance </Th> <Td> High School Musical </Td> </Tr> <Tr> <Th> Last appearance </Th> <Td> Sharpay's Fabulous Adventure </Td> </Tr> <Tr> <Th> Created by </Th> <Td> Peter Barsocchini </Td> </Tr> <Tr> <Th_colspan="2"> Profile </Th> </Tr> <Tr> <Th> Occupation </Th> <Td> Student Star </Td> </Tr> <Tr> <Td_colspan="2"> <Table> <Tr> <Th_colspan="2"> (show) Family </Th> </Tr> <Tr> <Th> Parents </Th> <Td> Vance Evans (father) Darby Evans (mother) </Td> </Tr> <Tr> <Th> Siblings </Th> <Td> Sharpay Evans (twin sister) </Td> </Tr> </Table> </Td> </Tr> </Table>
