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.

Because I'm playing Dirk Gently [ in Dirk Gently's Holistic Detective Agency], I'm so fond of Dirk. I really see Dirk's vulnerability, and you get that, more and more. You'll start to see a little bit more of Dirk's backstory, why he behaves the way he does, and why he's doing what he's doing. I see a lot of his vulnerability, his sensitivity and his insecurity.

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.

I'm a huge fan of [Elijah Wood] work and a huge fan of him, as a person. What's great about getting to know him is that he's just a really lovely, regular guy.

Max [Landis] writes in quite a heightened way, specifically for Dirk. There's a rhythm and a specific speed to it, and it was very easy to learn because it was so well-written. It just rolled off the tongue. There aren't many auditions that I go for, where I feel like I could actually do the part. But with this one, even though I was not quite sure how to pin Dirk down, I thought I could do it.

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.

You had to make everything much more truthful for the camera. With the stage it's a given that it's going to be theatrical.
