I used to be mouthy. It was all to do with being a northerner and from Manchester, which was suddenly a big deal when I was in my 20s. When I read some of the interviews I did back then, I cringe.
I'm not posh at all. I grew up in Sheffield but never managed to pick up the accent - which was careless because there'd be some cache now in being a northern playwright, but I missed out on that one.
I thought I had a pretty good American accent but I had a few sessions with a voice coach over there and she was picking up on a few things. Possibly because I've got such a strong Northern accent, I emphasise the wrong part of words so the idea is to work on my American accent.
When I went on air and people heard my accent, they all said it was really nice to have a northern voice.
The more cynical commentators on our careers would say that the northern accent has been the basis of our success. There's a certain authenticity to the voice - which isn't to my credit; I was just born there.
But I am Northern myself, and there is a certain rhythm of Northern speech that is very comical: that combination of the choice of language and the speech rhythm, which in itself is very funny.
I had people who said I was a brilliant producer but I wouldn't get on the news because I was too northern. But there was no way I was changing my accent - it is the key to my identity.
I love my accent, I thought it was useful in Gone In 60 Seconds because the standard villain is upper class or Cockney. My Northern accent would be an odd clash opposite Nic Cage.
