I love accents, but I find that I'm always changing my mind which one I like the most. It seems to be relative to what's happening in my life. For instance, when the South African cricket team were touring here, I loved listening to that accent.
I had a part in a Dylan Thomas play and it involved my having to learn a Welsh accent, so I loved that one for a while. As an actor, I've always listened out for various accents and tried to mimic them. It's fun to try and pick the slight differences between localities...
