Well, I don't think I've ever consciously come up with tricks and tools to, kind of, hide. I do think I'm a bit more vigilant, in terms of safety issues and things. And sometimes it is kind of nice to try to hold onto your anonymity.
I tend to get comfortable with the dialogue and find out who the person is in the script and try to hit that. People are sort of independent of their occupations and their pastimes. You don't play a politician or a fireman or a cowboy - you just play a person.
