When I was doing 'Eternal Sunshine of the Spotless Mind' I was asked, 'If there was one part of your life that you could erase, what would it be?' And I was so stunned by that. I thought: 'Nothing.' I would keep all the good bits and the bad bits, because those things made me who I am.
I was always quite good with accents - I always had quite a good ear - so from the age of about 13, I used to do a lot of voiceover and dubbing for foreign films.
The countryside, particularly, is very good for my head.
