David Krumholtz says he has stepped back from professional acting after decades in Hollywood, describing the decision as a relief while leaving open the possibility of redefining his career.
Krumholtz, known for Oppenheimer, Supergirl, Numb3rs and The Santa Clause franchise, said he recently sent what he described as a “definitive email” putting his acting career on hold.

He explained that he had feared leaving the industry because of financial uncertainty, but felt a “huge wave of relief” afterward. The actor later deleted his posts, but continued responding to supporters.
He distinguished between acting as an art and working professionally in Hollywood, saying he has continued to enjoy performing but no longer finds the business itself rewarding.

Krumholtz also expressed concerns about continuing to compete for roles that, in his view, could exploit an actor’s talent and reputation for diminishing returns. He argued that artists deserve fair compensation for work that contributes to employers’ profits.
Krumholtz began working professionally in the early 1990s and has accumulated more than 100 film and television credits.

His notable projects include Addams Family Values, 10 Things I Hate About You, Harold & Kumar Go to White Castle, Ray, Superbad and The Studio.
His longest-running television role came on Numb3rs, where he appeared in 119 episodes. He also played Isidor Isaac Rabi in Christopher Nolan’s Oppenheimer and most recently portrayed Zor-El in Supergirl.

Actor Garret Dillahunt expressed sadness while supporting Krumholtz’s decision. Krumholtz responded that he is “redefining” his terms and hopes to find a more rewarding passion.
Krumholtz said he is not quitting entirely, but is taking an indefinite break and considering whether there is another direction he should pursue. He has not announced a specific new career.
