Rob Gilby, managing director Disney Channel UK, said: "Music is one of the core drivers of Disney Channel's success as it's an integral part of every kid's life no matter where they live. The 'High School Musical' soundtrack is catchy, relevant and optimistic in a way that resonates with our young audience, which is why it is in such demand around the world and now here in the UK."
Leading up to the premiere weekend, Disney Channel UK launched creative programming events, interactive and online elements, a school outreach programme that furthers the "express yourself" message of the movie.
There is even set to be a Bollywood version of the movie, with the soundtrack re-recorded in Hindi.
The original was directed by Kenny Ortega, who is best known as the choreographer on 'Dirty Dancing' and 'Ferris Bueller's Day Off'. Disney is already understood to be planning a sequel.
