Zac Efron has reportedly signed a megbucks deal with Disney to star in the fourth installment of High School Musical.

The star has expressed his eagerness to shake off his squeaky-clean image, revealing in a recent interview that he is on the hunt for more adult roles after High School Musical 3: Senior Year.

But it seems that Zac has been tempted back to East High by a big money offer.

The actor is also set to star alongside Johnny Depp in the next Pirates of the Caribbean outing.

An insider tells The Sun, “Zac was extremely interested. But Disney realised they couldn’t make the fourth Pirates movie without Johnny.

“They had to offer him a small fortune to do it.”

Johnny is said to be receiving £30 million for his participation in the forthcoming film.
