Jon Hamm has been in Atlanta for a while now filming "Keeping Up With the Joneses," a buddy comedy with Zach Galifianakis.

UPDATES:

Jon's no stranger to Atlanta, having worked on "Million Dollar Arm" here a few years ago, and has popped up here and there since arriving for his current project.

A colleague tells me he was among the celeb guests cheering the Atlanta Hawks to a thrilling victory over the Wizards on Wednesday night. So were members of the "Captain America: Civil War" cast. That movie is filming in Atlanta at the moment as well.

UPDATES:

My friend Patrick Saunders, deputy editor at Georgia Voice, saw Jon Saturday at the Starbucks at Atlantic Station:

"I was standing on the corner of 17th and State Street waiting to cross when I heard a familiar voice behind me, turned and it was Don Draper himself, carrying a cup of coffee and walking by with a friend," Patrick told me. "They jumped into a white Escalade or similar SUV that was waiting for them and drove off."

Jon previously popped into Corso Coffee at Buckhead Atlanta, where he's shown above getting a cup of joe to go (in his own thermos, by the way).

"Joneses" has filmed in Peachtree City, off Defoor Avenue, the Dupont Commons community in west Midtown, and a downtown Atlanta hotel.
