Jon Hamm Calls John Mulaney & Nick Kroll 'Good Friends'

Jon Hamm suits up in gray while attending an AOL Build Series Event on Wednesday (October 12) in New York City.

The 45-year-old actor recently opened up about being listed as an understudy alongside John Slattery for Broadway’s Oh, Hello, starring his pals John Mulaney and Nick Kroll.

“It’s very smart – they clearly chose us for a reason! Those boys aren’t getting any younger, so you never know if there’s gonna be a fall backstage,” Jon recently joked to THR. “John and Nick are good friends of both John and I, so it’s a fun meta moment we were able to put into the show with them.”

FYI: Jon is wearing a Brunello Cucinelli suit and pocket square.
