One Oppenheimer star is stepping away from acting after admitting that he feels “frustrated” and “fed up.” The actor known for the Nolan epic as well as Supergirl announced the news this week.

David Krumholtz from Supergirl and Oppenheimer takes a break from acting

David Krumholtz appears to be stepping back from Hollywood for the time being. The veteran actor made the unexpected announcement on social media before deleting the post.

“I kinda sorta put my acting career on hold the other day. It’s been something I’ve been petrified to do for years. Specifically, the fear was that I’d go broke and not be able to handle being out of the game. But I sent the definitive email,” Krumholtz posted on Threads, per The Hollywood Reporter. “And gotta say, a huge wave of relief washed over me. Not sure what I’m going to do for money instead, or how I’m going to do it, but I just removed a humongous burden, one that I truly didn’t fathom the weight of until it was gone. Frustrated, fed up, fried.”

The post drew a lot of attention right away, and the 48-year-old stayed engaged by answering fans in the comments. Addressing the reactions, the Numb3rs actor explained, “The love and encouragement re: my last post is overwhelmingly surprising. Acting professionally is a very different concept than the exercise of acting itself. I’ve enjoyed every single minute of exercising the muscle. I’ve enjoyed the fanfare. There was a time when being competitive and self-involved really served my pursuit. That time has passed. Much to MY overwhelming surprise. There will always be great joy in the exercise. But for me, the profession has lost its gleam.”

As reported by Deadline, David Krumholtz went on to clarify that he’s “not quitting entirely,” noting, “Just taking a bit of a step back and an indefinite break. The stress of the moment has me wondering if there’s a higher calling to pursue. Thanks for the very kind thought. Means the world.”
