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.

I started to really enjoy the fact that [princess] Margaret was an exhibitionist. Even on a day-to-day basis, Margaret's costumes were always so much more dramatic and bold than Elizabeth's were.

[Princess Margaret] was loud, an extrovert, an exhibitionist, loved fashion, loved color, loved music, loved drama, loved the theater, wanted to be a ballerina or actress, was always the little one putting on the school plays, and [princess] Elizabeth reluctantly did it and got stage fright.

I watched her do speeches, but the only footage we could find of [princess] Margaret was archive footage, which was of her public presentation of herself.

[Queen Elizabeth] is just the granny queen! She's our granny queen who shakes people's hands!

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

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