Zac Efron Gets to Work on 'Dirty Grandpa'!

Zac Efron walks to his location on the set of his new film Dirty Grandpa on Monday (January 12) in Atlanta, Ga.

The 27-year-old actor was joined by his co-stars Julianne Hough, Robert De Niro, and Dermot Mulroney for filming that day. The company was rehearsing for a funeral scene.

Dirty Grandpa, which also stars Aubrey Plaza and Zoey Deutch, is about an uptight guy who is tricked into driving his grandfather, a perverted former Army general, to Florida for spring break. Look out for the film to hit theaters in June, 2016!
