Your source material is the people you know, not those you don't know, but every character is an extension of the author's own personality.

You know like it has its own personality, its own character.

The avant-garde theater is fun; it is free-swinging, bold, iconoclastic, and often wildly, wildly funny. If you will approach it with childlike innocence - putting your standard responses aside, for they do not apply - if you will approach it on its own terms, I think you will be in for a liberating surprise.

You gotta have swine to show you where the truffles are.

Old people whimper, and cry, and belch, and make great hollow rumbling sounds at table; old people wake up in the middle of the night screaming, and find out they haven't even been asleep; and when old people are asleep, they try to wake up, and they can't... not for the longest time.

Every part I play is just a variant of my own personality. No real character actor, of course, just me.
