People are so much more fascinated by the royal family generally than in England.

Once you start [filming] you have researchers who are constantly giving you information. Ultimately it isn't about impersonating or trying to be an image of somebody and more trying to capture the spirit and the soul of the person somehow.

That external struggle mirrors the struggle of this life force of energy that [princess Margaret] was.

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

That's exactly how I felt. So getting to suddenly know this young [princess] Margaret, who had this extraordinary life - it was sad and tragic and difficult and sort of astonishing and getting to know her young self was amazing because it completely defied all my expectations.

[Princess Margaret] was always trying to radicalize things.

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