Shetland star on season 8: 'It was always going to be really different'

But it's not just the on-screen action which has a different feel. Speaking to RadioTimes.com about the experience behind-the-scenes, Alison O'Donnell, who plays Tosh, said: "It was night and day, to be honest. It was always going to be really, really different because I had cut my teeth working alongside Dougie and learning how to do this job.

"I had grown into that iteration of the show and I felt very comfortable in that. I always felt like I could anticipate what was coming, so everybody knew that was all going to be out of the window [with this season]."

She added: "Ashley's approach was different, my relationship with her was different, and going into it I was feeling really out of my element and very nervous."

But it was also deeply satisfying for O'Donnell to throw herself into a new challenge after over a decade on the show.

"At the same time, I felt very awake," she said, adding: "It was nice to be reawakened and to a certain extent, start all over again, although at the same time I was able to bring a decade of experience of what this show is and what my experience of this show is, and Ashley's experience of everything she's done before, and we just tried to meet in the middle.

"It was a really, really thrilling process. I really enjoyed it."

In an interview with Radio Times magazine, Jensen acknowledged that there will be people who "miss" Henshall, but she assured fans that: "Shetland has kept everything that's wonderful about it, but it's somehow amplified."

She added: "It's lovely that it's two women leading the show. I love working with Alison, and bringing in my character shines a light on Tosh, so we see a different side to her."

Shetland season 8 airs on Wednesday 1st November at 9pm on BBC One and iPlayer. Ann Cleeves's Shetland novels are available to buy now.
