From the screenplay of ALL ABOUT EVE:
BILL
The Theatuh, the Theatuh-
- what book of rules says the
Theater exists only within some
ugly buildings crowded into one
square mile of New York City? Or
London, Paris or Vienna?
Listen, junior. And learn. Want to
know what the Theater is? A flea
circus. Also opera. Also rodeos,
carnivals, ballets, Indian tribal
dances, Punch and Judy, a one-man
band - all Theater. Wherever
there's magic and make-believe and
an audience - there's Theater.
Donald Duck, Ibsen, and The Lone
Ranger, Sarah Bernhardt, Poodles
Hanneford, Lunt and Fontanne, Betty
Grable, Rex and Wild, and Eleanora
Duse. You don't understand them
all, you don't like them all, why
should you? The Theater's for
everybody - you included, but not
exclusively - so don't approve or
disapprove. It may not be your
Theater, but it's Theater of
somebody, somewhere.
