From Guest Stars to Award Winners: 25 Famous Faces Who Got Their Start on Law & Order

As Law & Order steps confidently into its 25th season, the franchise carries not just a legacy of gripping courtroom drama but also a remarkable history of showcasing talent before Hollywood ever caught on. For three decades, its rotating cases have provided endless opportunities for actors — whether playing a victim, a suspect, or a witness — to cut their teeth. And many of those fresh faces went on to become some of the most celebrated names in film, television, and theater.

In fact, a 2025 SAG Awards segment paid tribute to this very phenomenon, spotlighting stars like Timothée Chalamet, Pedro Pascal, Zoe Saldaña, Bradley Cooper, and Sebastian Stan — all of whom can trace part of their journeys back to the iconic “dun-dun.” As Emmy winner Liza Colón-Zayas put it: “It was a very big deal to be on Law & Order. It’s a rite of passage.”

Here, we revisit 25 future award winners whose early appearances on Law & Order became stepping stones to acclaimed careers.

Looking back, it’s clear that the series has been more than just television comfort food; it’s been a launchpad for greatness.

From Cynthia Nixon’s subway shooter to Zoe Saldaña’s mafia entanglement, from Claire Danes’ teenage suspect to J.K. Simmons’ recurring psychiatrist, these guest roles became part of a cultural rite of passage. Law & Order didn’t just deliver justice on screen. It quietly shaped the careers of some of the most acclaimed actors of our time.
