Playing villains is very liberating because unlike the leading man, nothing is expected of you. Leading men have to look good, they have to behave in a certain way, they have to fulfill an audience's expectations. But as a bad guy, you have free license to take the audience by surprise. And that's what audiences want - they want unpredictability from their villains. The villain's job is to subvert it.

When I get home after being away for work, my wife always stuffs the fridge with loads of what she calls 'nibbles' - all the great things you can eat straight from the fridge, like chunks of cheese, slices of ham, bowls of hummus.

I like doing everything - theater and film, radio and TV, comedy and tragedy. I love it all. And I've never really planned anything - I've always looked at my job in a rather simplistic way. It's like being a plumber. One day you might be fixing an early 20th century showerhead that requires real detailed work. The other day you might just be clearing a sewer. Both jobs are very different, but all the tools come out of the same box. That's the way I look at acting.

There are many actors who have inspired me: Spencer Tracy for his incredible elegance and, of course, Cary Grant. But, there's also an Italian actor I admire a great deal: Alberto Sordi.

When I was younger I was always big; I was a fat boy at school. I had an early growth spurt, and when I went to secondary school I was tall enough to be a policeman.

The big stars I felt a kinship with were never the romantic leads. It wasn't Steve McQueen or Robert Redford - it was people like Walter Matthau and Anthony Quinn. My big hero was Tommy Cooper.

And I think it's because good cons are all based on the victim's need, and the successful con artist is the one, I guess, who can exploit that. I remember reading something about this, that one of the great traits of confidence tricksters is the level that they flatter their victim.
