I really enjoyed stepping into that side of [princess Margaret] and being silly and naughty and fun.

I remember somebody saying something to me about Frost/Nixon, when Anthony Hopkins does his famous speech, and the difference in the way Anthony did it was to dramatize, essentially, what was a documentary-style version of that speech. I remember someone saying to me, "There is artistic liberty."

I would argue [princess] Margaret is the tragic figure of the century.

I watched tons of archive footage of princess Margaret and listened to the music she loved; that was really immersive and brilliant.

[Princess Margaret] was always trying to radicalize things.

I did a lot before [being cast] because I knew how important it would be for playing somebody real, or attempting to - to show the team [the role] was something I would be fascinated to do. I read a couple of biographies and I watched everything I could find [about princess Margaret].

My dad is a big extrovert - he's a doctor - but he always loved [William] Shakespeare and he took us to tons of theater.
