'Unforgotten's Season 6 Trailer Digs Up a Fresh Case

PBS and Masterpiece are on a roll now that the end-of-year pledge drive has wrapped up and the first debuts for the 2025-2026 television season have arrived. Patience Season 1 has rolled out to solid enough reviews and an already greenlit Season 2, and Grantchester Season 10 is bubbling along happily with its new Hot Vicar. Meanwhile, the network is already looking ahead to mid-August, when the next batch of Sunday British offerings arrives, featuring Professor T Season 4, The Marlow Murder Club Season 2, and Unforgotten Season 6, all airing back to back. On Tuesday, June 17, Masterpiece debuted the trailer for Marlow Murder; one day later, it's Unforgotten's turn.

The series is riding a major high as it returns to PBS for 2025. Season 6 aired and streamed on ITV earlier in the year in the U.K.. The reviews, which I will not link to due to a significant season premiere spoiler (which American fans should get to experience cold if they want), reached a new level of critical praise despite the show's longevity. Part of the reason for this is the new life breathed into it by the change of guard from Nicola Walker as DCI Cassie Stewart to Sinead Keenan as DCI Jessie James.

Unforgotten's producers should be proud of their accomplishments. Despite how easy Doctor Who makes it look, changing out lead actors is not for the faint of heart; Death in Paradise and Grantchester have both now done it multiple times, and it never goes as smoothly as one might hope. Season 5 had its share of awkward moments, trying to cram in all the necessary plot beats of a changeover and a complex case. But even with the sometimes rushed moments, fans could see that the new duo was going to make a great team, and the first trailer for Season 6 confirms it.
