Holy Zac Efron Biceps!

By: Peggy Truong / April 24, 2013

Not a whole lot is known about Zac Efron’s latest project, Townies. But judging from Wednesday’s set photos — does it really matter?

Efron’s bulging biceps were put on display thanks to a tight fraternity shirt as he was spotted taking a break at the crafts and services area of the Los Angeles set.

According to IMDB, the comedy tells the story of a frat boy whose behavior affects a neighbor’s family life. Townies’ star-studded cast includes Seth Rogen, Dave Franco, Rose Byrne, Jake Johnson and Superbad’s Christopher Mintz-Plasse.

Efron, 25, can currently be seen in the new drama At Any Price, opposite Dennis Quaid and Heather Graham. The film opened in theaters on Wednesday.
