My character Lena is somebody who responds to people in a very simple way. I didn't have to take myself off to a darkened room to concentrate I just had to try and be open. It's an interesting subtle relationship.
Loki in 'Thor' is the most incredible springboard into a sort of excavation of the darker aspects of human nature. So that was thrilling coming back knowing that I'd built the boat and now I could set sail into choppier waters.
