Grantchester season 8 is on its way to ITV1 and PBS Masterpiece in 2023 which means more investigations and relationship rollercoasters for DI Geordie Keating and Rev. Will Davenport, played by Robson Green and Tom Brittney. 

It's again set in the late 1950s, and joining them will be the regular cast who appeared in Grantchester season 7, including Charlotte Ritchie, Tessa Peake-Jones, Al Weaver and Kacey Ainsworth, plus many new guest stars.

Robson Green says: "It’s so good to be back on Grantchester. A series that just gets better with age. Everyone involved is at the top of their game and this incredibly charming, likeable, dark and edgy show is an absolute privilege to be part of.”  

Tom Brittney adds: “I’m absolutely chuffed that we’re going ahead with another series of Grantchester and that I get to continue playing a character I adore so much. To be part of a show as well loved as this one, that is now in its eighth series, is an absolute honour.”

Interview: Robson Green on what happens in Grantchester season 8?

The stories in Grantchester season 8 range from an episode involving speedway racing to spying in the Cold War. The series will also be exploring the lives of invisible women and the very visible problems caused by Leonard’s new vocation which may, once again, find him battling the law.  

In a recent interview with us to promote Robson Green's Weekend Escapes Robson told us: "Yes, so in the opening episode something horrific happens to Will that changes his life forever. It's really shocking and has a profound effect on everyone around him, including Geordie. It also looks like Geordie’s being kicked out the station and that he’s going to have to hang up his detective hat because there’s some new young blood coming in with some different ideas. I’ve just watched the episodes actually and they’re as strong as ever. Everybody is at the top of their game and I just feel so fortunate that I’m nearly 60 and I’m making a living out of doing something like Grantchester. It’s a lovely show to do and as I enter the last third of my life I just want to do jobs that are fun and with people I love working with."
