People always make that mistake when they talk about theatre - the notion of the 'theatrical' meaning something separate from life. If it doesn't relate to life, it doesn't relate to anything.
Other quotes by Brian Cox
I did a film in which Andy Garcia and Michael Keaton both played the leads, 'Desperate Measures,' and interestingly enough it was their biggest payday. The film didn't do well, and it kind of marked their careers. They've done less since. It all changed.
I was living in London and I thought, 'There's nothing here for me anymore.' I don't want to become this actor who's going to be doing this occasional good work in the theater and then ever diminishing bad television. I thought I'd rather do bad movies than bad television because you get more money for it.
