If in my twenties I'd gotten one of the two-dozen roles that I did screen tests for and almost got, I think I would have become bored with the awards circuit, the whole hype machine.
Usually the characters I play are men of few words, who communicate in non-verbal ways.
I would literally climb out of the cradle while my parents slept, go and crawl off. I did this a couple of times apparently. I'd cross the road and into someone's house, wake them up banging pots and pans in the kitchen.
I know people who prepare their roles in such a way that they technically look ahead and memorize their gestures, and then they stick to it. Those that are technically proficient enough can make it seem natural, but they do that and don't really take in what other people are doing.
