Production
Before rehearsal began, Disney's High School Musical site put up a poll for what the viewers want to see in High School Musical 2. Due to that voting, Miley Cyrus will have a cameo appearance in the movie.
In early February, 2007, Ashley Tisdale, Corbin Bleu and Vanessa Hudgens were reported to be holding out for a more lucrative contract. Disney Channel representatives claimed rehearsals would begin on schedule, and by February 19th, the entire cast was on set and rehearsing in St. George and Salt Lake City, Utah.The cast wrapped up filming on April 13, 2007 and have since returned home.
In the first released trailer, the main cast is shown counting down the seconds until summer break. In a teaser, the trailer asks "Are you ready... for the start of something new?" before showing the High School Musical 2 logo along with the Disney Channel logo. An ad campaign, asking viewers to email their friends about the site to reveal a new poster, was also shown. Early scenes of the movie can be seen during the video for What Time Is It?.
Zac Efron confirmed that the singing voice of Troy Bolton will be himself only and not blended with the voice of Drew Seeley as in the first movie.
