After a three-year gap between seasons 3 and 4, Unforgotten fans will be pleased to know the show is not only renewed for season 5, but it's due to arrive on our screens within the next year or so. Those who've seen season 4 may understandably have mixed feelings about a fifth season, but it will be interesting to see what that new season looks like.
Spoiler alert: Keep in mind that some big things happened in season 4, and while we haven't mentioned those things YET, it's all but impossible to discuss the upcoming season 5 without mentioning a few details that could spoil your enjoyment of season 4. If you aren't caught up, we recommend not reading ahead unless you don't mind spoilers.
What's Unforgotten About?
For those who haven't seen it, Unforgotten follows a pair of London detectives as they solve serious cold cases involving things like murder and disappearances. DCI Cassie Stuart (Nicola Walker) and DI Sunny Khan (Sanjeev Bhaskar) play the lead roles, and each series follows a single case that carries over between episodes.
The series is unlike some crime dramas in that it also follows the emotional impact of the crime and investigation. We also see more of the investigators' own lives than in many “pure procedural” dramas. It's not just about the puzzle.
If you haven't already watched the series, you can watch it HERE on Amazon Prime Video and PBS Masterpiece in the US. In the UK, Unforgotten airs on ITV and ITV Hub.
What's Happening in Season 5 of Unforgotten?
Reminder: This is your last chance to look away before learning things you might not want to know about season 4 of Unforgotten.
Season 5 of Unforgotten will follow the devastating season 4 finale where Cassie was in a car accident and died of a brain injury. Given that so much of the series revolved around the close relationship between Cassie and Sunny, it's hard to even imagine how the show will continue without becoming a shadow of its former self.
Back in the fourth season, we saw Cassie returning from sick leave after a mental breakdown from the trauma of everything in her life. The case she'd worked was intense, and her father was diagnosed with dementia. The new case for the season focused on the murder of Matthew Walsh, a man whose headless body had been found in a trash pile.
We learned that Walsh wasn't exactly an innocent, and he had committed a few of his own horrific crimes before meeting his bad end. He had killed the brother of a suspect, and that turned out to be the reason for Walsh's murder.
Unfortunately, before the truth came out, Cassie was hit by a speeding car and suffered a major head injury. As she was in hospital, Sunny went on to finish the investigation. Sadly, Cassie would die in surgery in the emotional season finale.
Few details about the upcoming season 5 have been made available, but writer Chris Lang has mentioned in a PBS interview that the new season will be the most political one so far. He said:
It's the most political of the story so far, ‘political' with a small ‘p.' It really addresses where the UK is as a country politically, and it obviously introduces a new partner in crime for him, which is just lovely and refreshing. It's a woman, and she's pretty different from Cassie, that's kind of all I can say. She's at a very different stage in her life. She's younger. She's his boss again.
Who's in Season 5 of Unforgotten?
Delighted to be able to finally tell you that the brilliant @SineadKeenan will be joining the gorgeous @TVSanjeev to play D.C.I Jessica 'Jessie' James to his D.I. Sunil 'Sunny' Khan in #Unforgotten 5. Shooting started…about an hour ago. How lucky are we. pic.twitter.com/Alqo4vWROE

UPDATE: On March 14th, Lang tweeted to announce that Sinead Keenan will join the series as DCI Jessica ‘Jessie' James alongside Bhaskar as DI Sunny Khan. The Irish actress has previously appeared in shows like London Irish, Lip Service, and Being Human.
Of her new role, Keenan has been quoted saying:
I’m very much looking forward to working with the extraordinary cast led by the brilliant and incredibly lovely, Sanjeev Bhaskar. And I’m hoping that if I play my cards right I might even get to take a peek in Sunny’s backpack!
Barring any possible flashbacks, it's safe to say Nicola Walker won't be returning as Cassie. Walker and Lang decided together that Cassie would meet her end in the season 4 finale, and that makes it sound like Walker was ready to move on and close out any possibilities of a return.
Walker recently appeared in the series Annika, based on the BBC Radio 4 play Annika Stranded. The TV adaptation sees Scandinavian detective Annika Strandhed (Walker) solving crimes in the Scottish Highlands.
But what about the rest of the Unforgotten cast?
We can also expect to see the likely return of Jordan Long as DS Murray Boulting, Colin R. Campbell as DSI Clive Andrews, Lewis Reeves as DC Jake Collier, Carolina Main as DC Fran Lingley, Georgia Mackenzie as Dr. Leanne Balcombe, Janet Dibley as Jenny, and Michelle Bonnard as Sal, Sunny's romantic life partner.
There's no word on whether some of the recurring characters from Cassie's personal life will return in any fashion. It would be nice to get proper closure on all those little threads.
When Does Season 5 of Unforgotten Premiere?
Filming for the new season began a couple days ago (mid-March 2022), so it's too soon to have a precise date for the premiere of season 5. Based on the filming date, our best guess would be late 2022. Granted, the world has been a bit unpredictable the last couple of years, so there's no telling what might happen between now and then.
In the UK, expect to see season 5 of Unforgotten on ITV. In the US, it's likely the new season will air on PBS and PBS Masterpiece as the previous seasons have.
Will You be Tuning in for Unforgotten, Season 5?
After the way the last season ended, some people have sworn off Unforgotten for good. Are you one of them? Or will you be tuning in to see what the new partnership is like?
