Meanwhile, Macdonald said: "There's a lot of new characters and there's a lot of twists and turns. I think Jack and Harry [Williams, show creators] are really good at setting up a bunch of things and then they unravel as the series does. And yeah, I think it's very much the same.
"They do that amazing thing where there are one-off characters that come into this, like there were in season 1, that are just electric and brilliant and odd and exciting to watch."

Meanwhile, Dornan explained one of the reasons why it was crucial to set the new season in Ireland - rather than Australia, where the first was set - revealing this was one of the factors in his agreeing to return.
He said: "My thinking was, 'Where are we going? Like, if we're doing this, where are we going?'
"Because it was a bit of an upheaval to go to Australia, and the idea of going again so soon after… I mean, [other cast members] don't have kids, I have three kids. And I took them all with me, they went to school there, it was a big thing family-wise to do that.
"And the idea of doing that again so soon wasn't hugely appealing. But luckily, Jack and Harry [Williams, creators] had plans to make it something closer to home, and I probably approved those plans pretty quickly."
