Commenting on the announcement, Ortega said, "Peter Barsocchini's exciting script for 'High School Musical 3' called for the addition of three sophomore characters, so we set out on a massive casting search across North America and England to find just the right young actors to play the parts. We think these talented performers will bring lots of humor, new twists, and musical fun to the film. Jemma was one of the many young actresses that we met in London, and she impressed us with her singing and dancing, in addition to being very exciting and effervescent. Matt has a terrific personality, and a great sense of comedy and fun. And Justin had a great presence and charisma, besides being a wonderful comedic actor who could really dance. I am confident that the three new actors joining our original cast will help to bring great musical thrills, surprises and a lot of fun to Senior Year and the halls of East High."

Jemma McKenzie-Brown's previous television credits include a supporting role in the BBC production of "The Amazing Mrs. Pritchard." Matt Prokop has had featured film roles in "Marked," "Walking Miracles," "Somewhere Else" and "Four Square." His television credits include "The Office," "The O.C.," and Disney Channel's "Hannah Montana."
