The play has to work for the super fans, and not speak down to them, and yet it had to play to those people who maybe had never read a Harry Potter book or seen the films.

I've had a long association with the theater over the years but I had never produced a play and it was something that I'd always wanted to do.The movies moved away from dramas, and I think that I'm very excited by the opportunity to take smart writing that takes risks and see it on stage. It's exciting to see that engagement between the audience and the playwright.

In this new digital landscape, this sort of international marketplace, it's come full circle, and I wanted to take advantage of my talent relations on both sides of the Atlantic.

I think where Playground is heading is deeper into that marriage between stage, film and television, with the increasing number of people in the film business working in television, obviously something that we were very influential in starting and doing at HBO. And I think that that's the focus of where I see the company moving forward, continuing to explore that intersection of all that talent.

I think that the marketplace has changed in many dramatic ways but actually in some sense it's remained the same because the challenge of creating quality programming is the same, and I've always thought that if you follow the great material everything else will fall in to place.

I find it very invigorating having Ken Lonergan, who's an established, Pulitzer-nominated playwright doing Howards End, or Chris Hampton who's won an Oscar writing a TV series, or having an actor like Mark Rylance, who is probably England's leading theater actor, in the lead in Wolf Hall.

You never know, until you put a play up for an audience, whether it's going to work. Things you think will work don't, and things you're not sure about work really well.
