It's entirely to do with personality, I think. There are good directors who talk a lot, bad directors who talk a lot, and good directors who don't say much and vice-versa. It just depends on whether people respond to that personality and whether people have a willingness to do something for them.

The skill of a good actor is to make it always seem like you're in that fantastically spontaneous moment. Very often, a stand-up comedian has a different instinct, which is to reinvent. Once you've laid down some material, and made them laugh, you move on and find some new material.

I absolutely don't care about my looks and I'm so used to them that I wouldn't change a thing. I would end up missing my defects.

But this is where you get all the market research and things get in danger of becoming formulaic, and where you depend on brands and getting recognised actors. It's the thing that precludes risk very often, otherwise everyone would be avant-garde all over the place.

Sometimes to think about why some institutions are stable, it's interesting to go one generation back and look at the author of that stability.

Directors don't get to see other directors at work - they're the only one on the set. I've met directors who've asked me what another filmmaker is like. So, there's probably nobody better placed to make all the comparisons and to pick up stuff than an actor.

Doing a job, or even watching a film, can make a difference to your life, but I don't think it ever has an explosive impact where your life will never be the same again. It kind of seeps into your life, and perhaps realise you're a little more vigilant about certain things than you might have been.
