There are lots of actors who are posh and stick with that, and there are lots of actors who are cockney, and that's what they do. That's fine, but I don't think that could be said about me.

I think if you do a lot of interviews, you're laying yourself open. If you put yourself out, accept every invitation to every premiere, then you can't really complain when people knock on your front door and photograph you in the street.

I'm not saying that every night of the week, my husband, ex-husband, our children and I all sit around together like one big happy family. But we do see each other frequently, and everyone loves each other, and we are all friends.

Marriage and being a mother are absolutely crucial to my happiness and my life.

When you think about such fine actors as Maggie Smith or Michael Gambon, they do all mediums. I think it would be quite sad and a bit dull just to have to stick to one. I like all of them.

The funny thing about children is that, whichever room we're in, that's where they'll be. If I'm in the bath, they'll want to be in there too, playing with the toothbrush pot or brushing my hair.

When you get into your 40s, the roles do tend to drop off, and I've seen it happening to friends of mine. Hopefully it is improving, and there are female TV executives now who are championing women of all ages in leading roles. But I'm not counting on it.

I've stopped worrying about whether people think what I do is any good. I've taken stick in the past, and I've genuinely worried and got incredibly upset.

Things can change on a daily basis in television. You can be introduced to aspects of your character that you had no idea existed because they didn't exist a week before. The next week it might be taken away from you in some way that you can't control.

Botox and other fillers make everybody look the same, with the big cheekbones where they fill you up. It's much cheaper to have a fringe - it takes years off everybody.

I've nothing against stay-at-home mums, but I love going to work, I love what I do and I wouldn't want to start resenting my home life if I was staying home 365 days a year.
