Zac Efron Wants $8m-$10m For High School Musical 4

Zac Efron is reportedly demanding $8m - $10m to star in High School Musical 4.

The actor, 20, is said to have the salary increase in mind, even though HSM3 isn't due in theaters until Oct. 24.

"He's thinking in the $8 million to $10 million range," a source tells Life & Style magazine. "But it depends on how the movie opens and how desperately they want him back."

Efron -- who dates his co-star Vanessa Hudgens -- plays Troy Bolton, the popular student and captain of the basketball team, in the hit Disney show.

High School Musical 2 garnered a whopping 17.3 million viewers the weekend it premiered on the Disney channel. It set a new record, becoming the most watched basic cable program in U.S. history.

Later this year, Efron is scheduled to star in Paramount's musical remake of the film Footloose, which will no doubt raise his profile even higher. He has said that he would like to add his "own little bit of flair" to the role originated by Kevin Bacon.
