"High School Musical" is the musical film in which Adrian demanded Liu Sisi play the villain role, one of the series acquired from Disney. He isn't greedy; having a TV show and a series movie is enough. AC Media is still slightly behind Disney as an operator of family-oriented programs, hence the mention of poor digestion.
However, producing "Hannah Montana" and "High School Musical" and making them equally popular is not difficult; otherwise, Hollywood's professional teams could disband. Of course, the prospects for "High School Musical" are a bit vague because he placed a Chinese person in a major role.
