Apple TV Hit Tehran Scores Season 4 Renewal as Hugh Laurie Joins the Cast

Hugh Laurie is jumping back into high-stakes drama, this time on Apple TV+. He’s joining Tehran for Season 3, and Apple has already locked in a Season 4 before the new season even drops. Bold move, and a good sign they like what they’ve got.

Laurie, forever Dr. House in many minds, hasn’t shown up on the big screen since 2019’s The Personal History of David Copperfield, but he’s been plenty busy on TV with Avenue 5 and All the Light We Cannot See. In Tehran, he’s playing a character named Eric Peterson, and yes, the show is leaning into his gravitas.

"South African nuclear inspector"

That’s the job description for Peterson, which feels like exactly the kind of chess-piece Tehran likes to slide onto the board mid-game. Apple has a new trailer out now if you want a taste of the vibe.

If you’ve missed the first two seasons: Tehran follows Tamar, a Mossad hacker-agent sent undercover into Tehran to sabotage Iran’s nuclear program. The initial op went sideways, collateral damage piled up, and by the end of Season 2 she’d gone off-script and lost key allies. Season 3 picks up with Tamar trying to reinvent herself and claw back Mossad’s trust — basically survive long enough to finish the job.

• Season 3 premiere: January 9, 2026 on Apple TV+; new episodes every week through the finale on February 27, 2026
• Trailer: out now
• New addition: Hugh Laurie as Eric Peterson, a South African nuclear inspector
• Cast: Niv Sultan as Tamar; Shaun Toub as Faraz Kamali; Shila Ommi as Nahid; plus Season 3 newcomers Sasson Gabai, Phoenix Raei, and Bahar Pars
• Season 4: officially renewed and already in production; release date still under wraps

Between Laurie’s casting and the early renewal, Apple’s clearly betting on this next run. Given where Season 2 left Tamar, Season 3 sounds like a pressure cooker — and dropping a nuclear inspector into the mix is not exactly subtle. In a spy thriller, that’s kind of the point.
