I think quite often, being on the new set is not what you expect. The most serious film can be the most fun. The one that's supposed to be fun can be the most serious. I don't think there are any hard-and-fast rules. I just think it really depends on your director and what the general vibe is.

I enjoy just being cocooned in production and it's completely different to your other life that you have. I enjoy that. I enjoy being on the set and hanging out and talking to whoever we're working with and just being in the moment.

If you can jump up onstage and make people laugh, shouldn't you also be able to inhabit a character?

I've always been someone that sets achievable short-term goals. I've never been someone that's had a five-year plan, or a three-year plan. That just seems to lead to a lot of disappointment, and doesn't give you the chance to be flexible. So I've just always been someone that's sort of reassessed where I'm at, and set goals that are realistic. And luckily, I've had plenty of chances to recalibrate and adjust, and good fortune's come my way.

Having seen Justin's work on Bleak House, I knew that he'd be incredibly well prepared and interesting stylistically for this and that was definitely the case. It's very liberating for actors - and I can only speak for myself here - but he creates a very loose environment and he's a great collaborator.

I think the beauty of working with young people is they remind you of the spirit of acting and it's just a big play.

I do believe in reading signs if they're really obvious to you. Things happen. Someone will say something to you today in the morning and then later on that day someone will mention the same thing and then the next day someone will mention it again. There's a reason why three people have said something within twenty four hours.
