I could, I think, quite easily have gone to Oxford. I got four good A levels, but my father's income was such that I wouldn't have got a grant, and he wouldn't let me go to university, and that was the end of it.
As any actor will tell you, the hardest thing to do is small parts, because you focus all your attention and concentration on that small part. When you're playing the lead part, you don't have time to think about the whole of it, so you just have to steam on and get on with it.
