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.

I think Dirk [Gently] thinks that he's a brilliant detective, but he's the worst detective, ever. He does have this particular skill, which I suppose you might call a really bad superpower because it's just not very helpful. He is able to sense the connections between things and he's nearly always right, but the problem is that he never knows what to do with any of those messages that he receives from the universe, so he just acts on things and gets himself into terrible trouble, all the time.

The great thing about the show [ Dirk Gently's Holistic Detective Agency] is that there is so much more to be revealed. There are questions about what each of these characters actually know, and nothing is what it seems.

[Elijah Wood] has got such a broad outlook. It's so much bigger than just the acting industry.

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.

I'm a Brit and I just put myself on tape, back in London, for a very distant American project that I thought I didn't stand a chance of getting. And then, I got a call about a week after I had submitted my tape, just saying, "They really like you and want to screen test you." So, I flew to L.A. and did the screen test. And then, I met Elijah [Wood] and did a screen test with him. And then, I had a very nerve-wracking few days back home, waiting and waiting and thinking, "This cannot possibly go my way because that would just be too good to be true." And then, it did.

One of the joys of this show [Dirk Gently's Holistic Detective Agency] is that each of those characters could be starring in their own show. It's only as the show goes on that you realize how they interconnect. They're all moving towards one another inexorably, to meet at a certain point.
