Jon Hamm and Zach Galifianakis are in Atlanta filming a new movie, "Keeping Up With the Joneses," a buddy comedy about suburbanites who turn out to be undercover agents. The movie is filming in Buckhead this week.

The guys were spotted having dinner at Bone Lick BBQ the other night and Jon ran by Corso in Buckhead Atlanta Monday morning for some coffee. He brought his own thermos. Eco friendly!

Corso is owned by LDV Hospitality, the Manhattan-based group also opening Dolce Italian (late summer) and American Cut (early fall) in Buckhead Atlanta, and sources who happened to be there this morning said the "Mad Men" star was very gracious and friendly to everyone.

Hamm's been here before, for "Million Dollar Arm." Welcome back!
