As an artist, as an actor, as a writer, you have to use what's personal to you. You have to be personal about your work; otherwise, it doesn't ring true.
In my experience it's not essential to get on with the person that you're acting opposite.
If I wanted to work financially, I would have made a series of different choices. I do get offered lots of movies which you could make a lot of money out of. And I always say, 'Why would I do that, when someone else could do it much better than me? Why would I want to do an action picture? Why?'
