Interview with Robson Green on Geordie's woes in Grantchester series 7

Robson Green says: "Geordie is lost at the beginning of this series, he no longer has the safety net of family. He is detached from Cathy and the kids and he’s living with Will at the Vicarage, also feeling lost there and like a fish out of water. There’s a lot of scope for odd couple behavior.

Tom is definitely Jack Lemmon and Geordie is Walter Matthau. The situation Geordie is in lends itself to lots of levity but he is a shadow of his former self. He’s back to square one and almost a bachelor again and realizes he has to try and get Cathy back. It’s a very simple tale for Geordie — a long time ago he met the love of his life in Cathy, then he lost her and now he has to try and win her back. The one person Geordie seeks advice from, who he shouldn’t seek advice from is Will. There’s a funny irony being played out throughout the series. Geordie also gives Will relationship advice when his own marriage is falling apart. There’s a lovely line that sums it up for Geordie when he says "It’s not the notches on your bed Will but the miles on your clock and you’ve never got out of the driveway." That sets up the dynamic between the two of them. 

Will is pursuing Maya, which turns out to be problematic. As well as Will putting himself in jeopardy, this could jeopardize Geordie’s life and career."

On Geordie's relationship with Cathy, Robson adds: "Although they’re separated, Geordie is the eternal optimist! He calls this a ‘blip’ in the relationship which happens to a lot of couples, they go through their ups and downs and they have to be worked at, which is how he sees it.  Geordie is quite deluded when it comes to his relationship with Cathy, he thinks she’s just going to come back but the more time he spends away from her, the more detached they become and Geordie becomes more of a stranger, not only to Cathy but to their children as well. 

Everything that anchored Geordie and gave him his sense of worth and belonging and his reasons to carry on is disappearing. Geordie’s love for Cathy is as strong as it ever was but she has moved on, she’s liberated and found a new life and new freedom. She now has control over her own life which used to be dictated to by Geordie's work and by Geordie himself, to a certain extent, and Cathy is enjoying all of these changes and this evolution. Geordie not only loses a sense of family and Cathy but also a sense of himself. This is recognized by Will and Bonnie and everyone else around him and they are all trying to get Geordie and Cathy back together but they, themselves, are the only ones that can do this."

Tom Brittney says: "Will is very happy in his work and his life in Grantchester but he realizes that something is missing and he wants some excitement. He introduces Geordie to the underground world of Jazz clubs and whilst they’re there Will meets someone that changes his life in a lot of ways, for good and for bad.

"This series really tests Will’s romantic life and relationships. A person comes into his life and causes a lot of problems because when Will falls in love, he falls hard. Then someone else comes along, who Will wasn’t expecting and they throw a spanner into the works and he has a real dilemma on his hands of what to do. He needs to choose between following his head or his heart. 

Tom was delighted to be directing an episode for season 7: He says: "It was amazing! It was one of the most fun experiences I’ve had on a set, it’s something I’ve always wanted to do since I was young. I finally got a chance to do it. I couldn’t have asked for a better cast and crew to work with, they’re all my best friends and my family and we all really helped each other through the experience. The Executive Producers were always on hand if I needed help with anything. I was worried beforehand that I might not know what I was doing or that I might have been in too deep but I never felt like that but it all went a lot smoother than I’d anticipated."
