All About David Corenswet’s Wife, Julia Warner

Superman actor David Corenswet plays a man leading an epic double-life. The star has some experience there, because he keeps his off-screen world extremely private. Corenswet is married to his wife, Julia Best Warner, with whom he shares one child. But his Instagram is almost entirely promotion for the upcoming DC flick and he has shared very little info about his family.

Here’s everything that is known about Warner and her relationship with the superhero.

Like Corenswet, Warner is an actor. Per her LinkedIn profile, she studied Fine Arts in Theater Arts Acting at Point Park University in Pittsburgh. According to her IMDb page, she has also tried her hand at producing and directing, and has credits with The Baby Sitters Pub, Ratched, and Pretty Little Things.

In 2018, she wrote a tribute to her work at the Pittsburgh Playhouse.

She seems to be close to her family, and posted about cutting down the family Christmas tree with other Warners in 2020.

And she and Corenswet share a Cavalier King Charles spaniel named Ira:

“He’s less of a doggy, more of a toddler,” Corenswet told People, adding that the seven-year-old dog “has a wonderful mohawk, a natural tuft of hair right between his eyes, which is the reason he's disqualified from being shown [making him] adoptable.”

According to an interview with People in June 2025, the pair met as teenagers at a Pennsylvania summer theater program and had a “slow-burn” romance. They were married in March 2023.

In 2022, Warner shared a carousel of pics that included Corenswet.

Corenswet and Warner welcomed a daughter in 2024, though they have kept her name private. In his interview with People, Corenswet said, “I feel like I’ve been a dad for a long time, and just waiting for a kid to prove it. My dad was an enthusiastic father and stayed home with my sister for a period when she was very little, and was very good with kids. And so I think I just inherited that. I liked being a camp counselor, and I have terrible jokes that nobody laughs at.”

The baby arrived in close conjunction with the beginning of his Superman journey, prompting him to add, “Two big unknown things at the same time. And they were both great things.”
