David Suchet's Poirot was very charming, and, when I'm away in the U.S., those series remind me of being in Britain and being British on a Sunday night.

I grew up in the suburbs outside of Newcastle, and there were blank walls, and there was a lot of space to imagine - the fields and the motorways - so I used to sit and talk to myself as different people.

It's hard for us to imagine, as humans, that we'll become less powerful. But it'll be healthier for the planet and for the eco-system if that does happen. If humans are going to merge with machines, then let's get on with it. I love humans, but I also love dinosaurs - I'm pretty sure I wouldn't have wanted them to die out, either.

Transformation as a female actor is allowed up to a certain extent - as long as they can still recognize you on a red carpet. For a woman to be a shape-shifter, and to be that malleable in spirit, is really not OK with the patriarchy.

I've worked opposite so many male actors whose egos have been so delicate that it was just so hard to do the work.
