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

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.

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.

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.

I read the script [of Dirk Gently's Holistic Detective Agency] and went, "I haven't read anything this good, in a long time." I thought it was absolutely brilliant. The dialogue is so sparkling, smart and witty. You also have these insane, crazy characters, like energy sucking vampires and holistic assassins. It's all completely weird.

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.

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.
