I count 'Underworld 4' as my training period for 'Total Recall.' I do think it was hard because I didn't realize how tired I was. It is quite a lot to sustain that kind of physical work over nine months altogether and by the end of it, I definitely felt like I had aged quite a bit in that year.

I'm not going to experience the reality of hardship that sometimes my characters live in. I'm very cautious about that.

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 just adored working in London. It was in London where I first had the idea of making a film.

I mean, we are tribal by nature, and sometimes success and material wealth can divide and separate - it's not a new philosophy I'm sharing - more than hardship, hardship tends to unify.

When I read the script it was extraordinary and to work with Yorgos [Lanthimos] again was amazing.

I think there were six or eight weeks between 'Total Recall' and 'Seven Psychopaths.' I was at home in Los Angeles for 'Seven Psychopaths,' so it was the first time I had worked from my house here so it was great to be around the kids.
