Zac Efron worked on "Dirty Grandpa," about a guy who road-trips with his lewd and lascivious grandfather (Robert DeNiro) in metro Atlanta and in Tybee Island earlier this year. To get into their characters they both went topless.

And now Zac is back.

His next project, filming here now, is "Neighbors 2: Sorority Rising," with Chloë Grace Moretz, Rose Byrne, Dave Franco, Selena Gomez and Seth Rogen.

The project has been underway in both Marietta and Dunwoody this week. The original “Neighbors” was about a couple with a new baby who battle with the fraternity house denizens next door.
