I personally would like to bring a tortoise onto the stage, turn it into a racehorse, then into a hat, a song, a dragoon and a fountain of water. One can dare anything in the theatre and it is the place where one dares the least.
-Eugene Ionesco

The color, the grace and levitation, the structural pattern in motion, the quick interplay of live beings, suspended like fitful lightning in a cloud, these things are the play, not words on paper, nor thoughts and ideas of an author, those shabby things snatched off basement counters at Gimbel’s.
-Tennessee Williams 

I think theater ought to be theatrical … you know, shuffling the pack in different ways so that it’s — there’s always some kind of ambush involved in the experience. You’re being ambushed by an unexpected word, or by an elephant falling out of the cupboard, whatever it is.
-Tom Stoppard
