At the end of the day, it's all one version of telling a story. I treated this as if it was a two million dollar independent film. I did a lot more physical work than I'd probably have to do for a two million dollar independent film with four months of training and stuff. But as far as the character's psychology or emotional life goes, I treat it just the same.

I hadn't really met Colin [Farell]. It's really weird to say: 'Oh, hello, I'm Kate...I'm Colin.. shall we?' That's a bit strange. Len was fine with it. We've gone through this experience with Scott Speedman before on the first Underworld move. It was our little version of swinging. We survived that.

I don't go to the gym or practice yoga. And the closest thing I have to a nutritionist is the Carlsberg Beer Company. I just have the appetite of a pigeon.

I didn't work with any of the beasts [ "Fantastic Beasts"], I didn't have much green screen, but I loved working on it. I'm excited to see it myself.

An actor said recently that, unless you're a parent, you shouldn't play a parent in a film. I don't know who said it, but I disagree. I understand that maybe there are aspects that you don't understand, or maybe this actor or actress had a really strong recent experience with having their first or second or third born child. I don't know. As a dad, I get that. I get that there is no love like it. But, at the same time, love is love.

I'm enjoying [my career]. If anything I'm aware that the pressure of the first, I suppose, six or seven years I was in America - I mean that energy of having such a rapid and ascending celebrity - it's not there anymore. It's the end of that chapter and now I'm just enjoying the work probably more than I ever have and yet I'm simultaneously less attached to it I think, which is kind of a strange state of grace to be in.

If you need to get in physical shape for a film and you have to maintain that for six months, at the start of the film, I was never able to do it.
