Essentially, I'm untrained, so I just go with my imagination and try to put myself as solidly as I can into the shoes of whatever person I'm going to be playing.
I know that every actor that I know, when Daniel Day-Lewis does a film, and he doesn't work that often, but we run to the theater to see what he's up to, and with such delicious excitement. The same goes for Meryl Streep.
Fortunate indeed, is the man who takes exactly the right measure of himself, and holds a just balance between what he can acquire and what he can use.
