More than one thousand kids from around the world tried out for High School Musical 3: Senior Year, and after an extensive search Disney has picked three of them to become the stars of tomorrow. The three new talents will play sophomores at East High, bringing some much-needed fresh blood to the set. Avid Disney watchers will recognize Matt Prokop from Hannah Montana, but British-born Jemma McKenzie-Brown is a little harder to place (her acting creds include work on BBC). Justin Martin, the third addition to the cast, was seen in ABC’s A Raisin in the Sun.

Director Kenny Ortega says the three newbies will bring a lot of “musical fun” to the film, claiming that Jemma offers impressive singing and dancing. Ortega boasted of Matt’s comedy skills and Justin’s “presence and charisma.” The movie will hit the big screen in October, with filming set to being in Utah within the next few weeks.
