David Harbour looked a bit beefier than usual on the set of his new show while filming in Atlanta on Thursday.

The Thunderbolts star, 50, who dropped nearly 100 pounds a few years back, showed off a noticeable tummy bulge beneath his brown, peach, and green striped golf shirt.

The actor was also dressed in dad-friendly tan chinos and gray sneakers as he crossed the set.

The Emmy nominee is starring in the upcoming HBO/Max series DTF: St. Louis, a dark comedy about three middle-aged people caught in a romantic triangle that turns deadly.

Despite his past weight struggles, it appears Harbour didn’t regain the weight for the role.

Jason Bateman, 56, is also starring in the series, along with Linda Cardellini, 49. 

Abbot Elementary star Chris Perfetti and Wednesday actress Joy Sunday have also been cast.  

DTF St. Louis has been in development for more than two years and has gone through some changes.

It was originally called My Dentist’s Murder Trial, based on a 2017 story in the New Yorker by James Lasdun.

Harbour signed to to that project along with Pedro Pascal, but The Last of Us star exited the project and it has since evolved from one based on a true story to fiction. 

Both Harbour and Bateman are executive producing the series. 

In an interview with The New York Times, Harbour spoke about how working on series and films has messed up his body clock. 

‘I was such a theater rat in my 20s. You’re out after the play till 4 a.m., so I would sleep in until 1 p.m,’ he explained

‘Now I’m a more film and TV guy, so you’re up early at 6 in the morning. But I still have that beast inside me that wants to sleep till 1 p.m. every day. I feel no shame,’ the actor said.

To help navigate the early call times, the Stranger Things star admitted he keeps himself caffeinated via coffee.

‘I drink it all day long. My doctor has told me to knock it off, but it is the last vice I have,’ declared the actor, who has been sober since age 24.

‘I have an assistant and she does a lot of great things for me, but probably the No. 1 job is she brings me too many Americanos throughout the day.’
