The whole nature of the show [ Dirk Gently's Holistic Detective Agency] is that everything is connected, and everything is interconnected. You have all of these strands with all of these characters, and you watch the characters interact and you wonder, "What do they have to do with each other? How does any of this link?"

I have been out of drama school for 13 years, so there are 13 years worth of graduates behind me.

I'd seen Elijah [Wood], when I was a little boy, in The Good Son. And then, I was a huge fan of The Lord of the Rings. It took awhile to get over that whole, "That's Elijah Wood - Frodo, from The Lord of the Rings." I was a mega fan of that. I went to the all-day screenings of the director's cut, where you could see the really long versions of all three movies, in one day.

To me, Elijah Wood is one of the best actors of my generation. He's so incredibly present and in the moment, when you're working with him, and then we just chat away about anything off camera because he's a lovely guy.

Like the Elizabeth I play, Queen Elizabeth is a monarch who actually moves with the times. She gets new information, assimilates it, and changes in order the fit in with the way the world is moving. I admire that.

We did every scene together, every day for four months, and it could have been a disaster, if we didn't get on, but we clicked straight away. Elijah Wood is just the nicest guy.

Elijah Wood is interested in people, in life and in music.
