Time series 3: 'Masterpiece' BBC drama starring Siobhan Finneran reveals new cast as filming begins
2026 is going to be an AMAZING year for drama on BBC One
Time series 3 has started filming, and the BBC has announced who will star alongside Siobhan Finneran and David Tennant in the cast.
Late last year, it was announced that Jimmy McGovern’s award-winning drama Time will be returning, after the huge success of series 1 and 2.
The first series of the drama starred Sean Bean and Stephen Graham as prisoner and seasoned prison officer. It aired in 2021 and, quite rightly, won multiple awards, including the 2022 BAFTA for Leading Actor and Mini-Series.
Series 2 followed in 2023. This time, it was set in a female prison and starred Jodie Whittaker and Bella Ramsey. Here’s everything you need to know about the upcoming series 3 of Time on BBC One.

When is Time series 3 coming out?
Time series 3 doesn’t have a confirmed release date yet, but with filming beginning this month, it’s hoped it’ll premiere sometime in 2026.
The show comes from multi-award-winning screenwriter Jimmy McGovern, known for his work on Unforgivable, Cracker, and The Street. Shook’s Samuel Bailey acts as co-writer.
Andrew Morrissey, Executive Producer for BBC Studios Fiction, said: “It is a privilege to be making a third series of Time with such a fantastic team. We are excited to introduce the audience to a whole new part of the prison system. Once we started the research, we knew there were stories that demanded to be told.”
What’s the plot?
This time, the drama takes place in a young offenders’ institution (YOI), and will explore the impact of locking up teenagers and the effects on those who look after them.

Prison Chaplain Marie-Louise is back as the only recurring character in all three series. She arrives in the YOI having lost her faith.
The BBC tells us: “When tragedy strikes within the prison, Marie-Louise clashes with veteran officer Bailey, a man in the midst of his own crisis. Bailey knows more about the circumstances that led to this major incident – but will he come clean before the guilt gets too much?”
Meanwhile, two teenage young offenders, Peter and James, struggle through the terrifying first weeks and months of their incarceration. James must face his broken parents after an unforgivable act of violence, while Peter must tell the truth about the death of an innocent man…
The pair forge an unlikely friendship which will shape their futures. But, in an increasingly unstable environment, is change ever possible?

How many episodes will it be?
Like the previous two series, Time series 3 will be three episodes of one hour each. Reader, the series are never long enough.
The show will air on both BBC One, BBC iPlayer, and BritBox. Robert Schildhouse, President of BritBox, said: “We’re excited to partner with the BBC on this next chapter of the acclaimed series. It features David Tennant and Siobhan Finneran in roles we know will be powerful and unforgettable.
“With Jimmy McGovern and Sam Bailey’s masterful writing and an exceptional cast coming together, this third season will be a must-watch.”

Who’s in the cast of Time series 3?
Time series 3 will star David Tennant as Prison Officer Bailey.
He barely needs an introduction, but TV fans will know him for Broadchurch, Rivals, Good Omens, The Hack, Staged, and countless other respected performances. Of course, he played The Doctor in Doctor Who (0n and off) between
Happy Valley favourite Siobhan Finneran reprises her role as Marie-Louise, a prison chaplain. She is the only character that will have appeared in series 1 to 3 of Time.
Series creator and writer Jimmy McGovern said: “Siobhan Finneran is back! And we’ve got a wonderful leading man in David Tennant. And a brilliant director in Paul Whittington. I think it’s going to be wonderful.”
Vinette Robinson (Boiling Point, The Lazarus Project) is one of the third series’ newest additions, and she’ll play Erica. The extended cast also includes:
- Jo Joyner (Little Disasters, Stay Close) as Nicola
- Daniel Ryan (Such Brave Girls, The Bay) as Custodial Manager Jennings
- Warren Brown (Ten Pound Poms, The Responder) as Albie

Series 3 will feature six debut performances from Ollie McNulty, Chukwubuikem Molokwu, Victor Zhao, Paul Smith Junior, Finn Kearns, and Jack Barnes
“It’s been an absolute honour to work with Jimmy on Time series 3, and with the brilliant cast put together by the team, I think this series will be just as impactful and devastating as Time 1 and 2,” Bailey said.
“I’m particularly excited for audiences to meet the lads playing our young offenders, who are all remarkable actors that I know we’re going to be seeing a lot more of in the future.”
