Zac Efron -- His New Film Is Painful, Injures Wrist On Set

As if making all those ridiculous "High School Musical" movies weren't grueling enough, Zac Efron's latest film role is turning out to be a major pain in the ... wrist.

The 25-year-old hunk was spotted with a heavily bandaged right hand on Thursday after falling and hurting his wrist on the L.A. set of his new flick "Townies."

Even with the injury, Zac appears to be lookin' fine ... as always.
