I come from a family of scrap metal dealers, so becoming an actor seemed like a ridiculous thing to do, but I'd found the thing that gave me a kick, and I quickly became obsessed with it.
'The Split' is actually really hopeful - although it's left me reeling slightly, thinking about what we do to each other in the name of love, within the contract of marriage.
My two girlfriends from university, Sue Perkins and Sarah Phelps, are both in the business - and are both stupidly busy. We talk on the phone a lot and try to get out to dinner together, but our preferred venue is one of our kitchens with a lot of tea.
'Unforgotten' was a bit of a no-brainer. I'm a big fan of crime dramas, but often the 'investigation' part goes much too smoothly - and you don't get that with this.
I am not a morning person.
Before I had my son, I became obsessed by this painting I'd seen in an art gallery. It was a lot of money, but I felt such a rush of adrenaline when I wrote the cheque to buy it. I thought I was going to gaze lovingly at it forever, but after just two weeks, I realised I didn't really like it any more.
