I'm by nature someone that quite likes to understand how things are working, likes some sense of structure, and I've fallen into the worst possible trade for that.

I've never been someone that was sort of blessed with an innate talent of just being able to do things. I had to work at it and learn from mistakes.

I think all actors have a similar deal. You want some people who understand. Although it looks great - and is great - there are also shoddy moments when you feel really rotten, and when it's going well, you're not allowed to complain.

The problem with motor neurone disease is they don't know when it starts. People go into hospital having fallen but get wrapped up and sent away, unless they're seen by an incredibly astute doctor. It is only when several things begin to go wrong that it'll be diagnosed.

Filming is about continuing to be alert and to think, and I find it quite exhausting.

If you are playing someone living, it is a different type of judgment. However much work you do, it is not a documentary. There will be things you can't get right, and ultimately, you have to take a leap because - you weren't there.
