His Dark Materials star Amir Wilson teases "heavy" and "emotional" final episode

"I think there'll be a lot of tears."

His Dark Materials will close out with a "heavy" finale, according to Amir Wilson.

Set to premiere on BBC One in the UK this weekend, the third and final season of the epic fantasy drama brings back Dafne Keen as the heroic Lyra Belacqua, who was abducted by Ruth Wilson's ruthless Mrs Coulter at the end of season 2.

Now it's up to Amir's character Will Parry to track her down, as Lord Asriel (played by James McAvoy) gets ready to wage war against the all-powerful Authority.

Teasing the show's grand finale, Amir exclusively told Digital Spy: "It was an emotional rollercoaster, really. I mean, it was hard to be emotional, because we were filming in Spain. We shot the last episode in the south of Spain, and it was beautiful.

"It had to look like paradise. We went to the south of Spain in Andalusia, and filmed in these amazing, amazing locations."

He continued: "The last episode is heavy. It's emotional. I think there'll be a lot of tears and stuff. There certainly was on my part and Dafne's part when we were filming it.

"I think it's a beautiful, beautiful episode. A really, really beautiful episode. And I think people are going to like it."

For readers who've had the pleasure of losing themselves in Phillip Pullman's original book trilogyNorthern Lights, The Subtle Knife and The Amber Spyglass – the good news is that it'll all unfold in a "pretty similar" fashion on screen according to Amir.

The last-ever episode is correspondingly titled 'The Botanic Garden'.

His Dark Materials airs on BBC One in the UK and HBO in the US.
