John Mahoney

What I mostly do is take the script, analyse the hell out of it, see what's in there, see what kind of person I'm dealing with, and then forget I'm playing a father and just play a person who exemplifies all those things.

To ask questions can become the laziest and wobbliest occupation of a mind, but when you must yourself answer the problem that you have posed, you will meditate your question with care and frame it with precision.
