James Norton has admitted that he developed a bit of a ‘bromance’ with his Grantchester co-star Robson Green.

The Happy Valley actor plays vicar Sidney Chambers, who teams up with Robson’s straight-talking copper, Inspector Geordie Keating, to investigate crimes in the sleepy village of Grantchester in the 1950s.

James told whatsontv.co.uk: “Robson’s had amazing successes throughout his life in music, telly and film and you worry that that kind of person may bring a bit of hubris and ego to the job. But he couldn’t be further from that, he’s so humble and down to earth.

“I’m loathe to say this, but we sort of had a bit of a bromance. We ended up going off to Wimbledon together and having a lovely time.”

When asked if he’d like go fishing with Robson – famous for his popular Channel 5 series Extreme Fishing – James replied: ‘I’d love to – can you ask him?”

Grantchester begins on Monday, October 6 at 9pm on ITV.
