Kicking off another day on the job, Zac Efron reported for duty on the Los Angeles set of “Townies” Wednesday afternoon (May 8).

Joined by costars Rose Byrne, Seth Rogen, and Dave Franco, the “Charlie St. Cloud” star looked cool and casual in a white t-shirt with grey trousers.

During the course of the shoot, Zac and his buddies seemed fascinated by a bunch of big exercise balls, tossing them around during a break.

Per the synopsis, “Townies” is “a comedy centered on a frat boy whose behavior affects a local neighbor's family life.”
