I think you have to be flexible above all as an actor; different characters have different demands, actors that you work with are different in their approach, or how you get along or don't get along with them.
Some actors learn the habit of promoting themselves as a brand - by dressing in a certain way, by going out with a certain person - it gives them what they obviously want, which is to keep a level of fame. I'm not putting it down.
Being an actor, imitating to the point of inhabiting the lives of others, may simply be a way of continuing to do what I learned to do as a boy - to travel, mentally and physically.
People talk about method actors, meaning someone that's prepared very, very well, or whatever they mean when they talk about it. But the right method is whatever works for you. And what works for me on any given day is going to be different.
The best thing an actor can be is flexible, because all directors are different and all actors are different.
I love rehearsing, but a lot of directors don't, and some actors don't.
I have no idea what 'method actor' means.
Sometimes you look at a movie and you can see that the actor or actress said, 'I'm taking this onboard because I'm making a ton of money, and not because it's going to be something special.'
In the end, the actor's main power is the power to say, 'No.'
Most actors can't make any kind of living.
