Professor T Season 4: Filming Wraps, Cast Returns, and What We Know So Far

The eccentric criminology professor from Cambridge is back on the case — and his world is about to get even more complicated.

Fans of Professor T. can finally breathe easy: season 4 is officially on its way. The beloved ITV crime drama, starring Ben Miller as the razor-sharp but obsessive Professor Jasper Tempest, has completed filming and is now gearing up for release.

A Quick Refresher: Who Is Professor T.?

Over three seasons, viewers have watched Jasper Tempest — a brilliant criminologist with OCD who lives with his formidable mother — lend his mind to the local police force. Along the way, he has cracked gruesome cases, fallen in and out of love, and even endured time behind bars for a crime he didn’t commit.

The series may have garnered mixed reviews compared to Britain’s heavyweight mystery dramas, but its character-driven storytelling and standout performances have earned it a loyal fanbase. With just six episodes per season, Professor T. has mastered the art of concise, tightly written crime stories that keep audiences hooked.

Filming Has Wrapped — Straight from Ben Miller

The biggest update came straight from Ben Miller himself. On July 18, the actor posted a lighthearted Instagram photo — shorts, tie, sandals, and all — celebrating the end of production:

“It’s a wrap! Season Four of Professor T is now officially in the can. Thank you to all our amazing cast and crew! We can’t wait to show you the results… First, though, I need to take an ice bath. And consider playing a detective who doesn’t wear a wool suit in 30-degree heat.”

The post confirmed what fans had been hoping to hear: season 4 is not just happening — it’s already in the bag.

Season 4 Was Officially Confirmed Back in February

The renewal of Professor T. was announced in February 2024 (via Variety), following a third season that wrapped in May 2024. Drawing audiences of over four million on ITV and selling to nearly 120 territories worldwide, the series has proven to be an international success.

Who’s Coming Back?

While ITV has yet to release a full cast list, several key characters are expected to return alongside Ben Miller, including:

• Barney White as DS Dan Winters

• Frances de la Tour as Adelaide Tempest

• Juliet Stevenson as Dr. Helena Goldberg

• Sunetra Sarker as DI Maiya Goswami

However, fans will remember the shocking loss of Emma Naomi’s DS Lisa Donckers in season 3, leaving a major hole in the team dynamic.

What Can Fans Expect in Season 4?

Plot details are being kept tightly under wraps, but given the series’ track record, viewers can expect:

• New cases that test Jasper’s intellect and moral code.

• Shifting team loyalties in the wake of Donckers’ death.

• A deeper look into Jasper’s personal life, as he balances his lectures, his work with police, and his complicated family ties.

When Will Season 4 Air?

ITV has not yet announced an exact release date. However, with filming complete, a 2025 premiere seems highly likely.

In short: Professor T. is back, Ben Miller is ready, and the wait for season 4 won’t be too much longer. Prepare for another round of witty, high-stakes crime-solving — and maybe a few surprises along the way.
