I'd seen her name on a call sheet for so many years and been called Jo so many times. If people said Jo in the street, I used to turn round because I was so used to being called Jo for five years on Spooks. You do get so used to being called something. Often, it was someone calling their young son... but sometimes it was people calling after me because they recognised me from the show. So, it was a big deal when it happened and it was quite an emotional end.

Anger makes people feel uncomfortable, because the minute somebody shows it, it puts you in a position where you can't laugh or make light of something... not to trivialise it I don't mean. But your reaction to anger is supposed to be fear or returned anger. So, you're really trying to control a situation when you show anger and it's a very weak position to take. It often works on people who aren't in a position to fight back.

Working with different people anyway is like life and meeting different people... as long as you can be empathetic, you can take a bit of them on and see what you can do to help their process. That said, my relationship with Woody Allen was trying to hang on his every word so that I could tell everybody what he said afterwards. But certainly, he was a very good example of somebody who you didn't hear talk above a very low volume for the entire time he was on-set.

What I've grown to hate in my 'old age' is shouting directors. I find anybody who screams and shouts to be difficult to work with... especially because the people who scream and shout tend to do it at runners, and not at the main actors. They make a great amount of noise and it's often at someone who is an easy target. I love working with people who are calm, even if my role is peripheral. I like people who realise that this is just a film... that we're not going over the top in No Man's land and screaming for our lives. There's just nothing to be gained by volume.

I'm doing The Physicists, which is great, and I do have my agent to thank for that because a lot of agents try and talk you out of doing theatre. They don't push theatre because you can make more money doing television, whereas theatre wages are pretty shocking. But it's something I've always been keen to do and have been encouraged to do so, which is nice.
