There is no way I'd have wanted to live in the Twenties. It was really crap for women.

I don't really get recognised very much.

In a way, it's good not to be recognised as much off screen.

I grew up listening in awe to stories of their wartime adventures. My granny, Joan, was a journalist and wrote amazing letters to my grandpa when he was a prisoner of war, while my nana, Mary, was a Land Girl, then a Wren. They were so independent, resilient and glamorous.

There's something about wearing clothes that your great-grandmother might have thought were nice that makes you look older.

We all have hierarchies at work - even on set, the runner would never walk up to the director and ask for a cup of coffee.
