Cast member Zac Efron from the movie "High School Musical 3: Senior Year" poses for a portrait in Los Angeles October 12, 2008. Efron says he wasn't much into sports at school, had to be dragged to his senior prom and was really a bit of a goofball. So becoming a global "tween" idol by playing a basketball star who wins the heart of the prettiest girl in school in the blockbusting "High School Musical" series has been a shock. [Agencies]
