Seven years later, theHis Dark MaterialsTV show is about to enter itsthird and final season.

Someone asked me after the delivery of Season 1, What were you afraid of tackling in this adaptation?

I said nothing in Season 1 made me feel afraid because I had the mulefa coming.

His Dark Materials Season 3

Its the fact that the books are so special and they are so beloved.

And so, your responsibility to that source material is intense and tender, and meaningful.

I think we successfully have made the third season very emotional, says Tranter.

Dafne Keen as Lyra in His Dark Materials

For me,The Amber Spyglassis essentially about love.

And sometimes, those questions are posed delightfully intriguingly.

And other times, its kind of like, What the hell is dust?

Amir Wilson as Will in His Dark Materials

And what does the prophecy mean?

And why is this important?

I think, in the third season, we successfully answer all of those questions.

And what does Pullman think?

Hes always clear about whats really important to him.

We always ask if were going to step away [from the source material].

And, sometimes, hes like, Yes, thats fine.

And other times, hes like, Absolutely not.

Hes just been brilliant.

It doesnt matter how brilliant the other things are, says Tranter.

If you havent got the drama and character right, then it will be for nothing.

His Dark Materialshas helped define the first phase of Bad Wolfs history as a company.

I think what it taught us is courage and faith and conviction, she says.

When we started onHis Dark Materials, everyone said to me, How are you going to do it?

And I was kind of like, I dont know, but I do know that we can.

Keep looking towards the horizon and just keep going.

And venture to enjoy the journey.

Den of Geek: What can we expect from Lyra in Season 3?

Dafne Keen:Id say Season 3 is the biggest journey that Lyras ever been on.

She goes through different worlds; she has her first romantic thing.

Its all very exciting for Lyra and also very terrifying and also very sad and very dramatic and fun.

Youve grown up on this production, which is a story about the experience of growing up.

What has that been like?

In a brief chat withDen of Geek, Amir Wilson bids farewell to his character andHis Dark Materials.

Den of Geek: Where do we find Will when Season 3 begins?

His experiences, especially at the end of Season 2, definitely changed him.

He knows what he wants and why he wants it.

What were you most excited to do in Season 3?

I was really excited to do the Land of the Dead stuff.

Reading about that whole world, I was really excited to go and film that.

What was it like filming those last intense, heartbreaking scenes between Lyra and Will?

It is sad, but Id known it was coming because of reading the book.

By the time it came, I felt pretty ready to do all the filming.

At the end, it was sad to say goodbye.

What do you think viewers have to look forward to in this final season?

Love, loss, and death are three words to describe the series.

And I also think the introduction of a lot of new worlds and new characters.

Everyone has a lot to look forward to.

His Dark Materialsseason 3 will premiere this December on HBO and BBC.
