Why Movies?

"There comes a time to turn mother's picture to the wall and get out."
-Brad Dexter in "The Magnificent Seven"

Why am I discussing movies? Why not? Literature is a closed shop. The lit world is impervious to change. There's no room whatsoever in literature for new ideas. Even so-called "outsider" writers fear change and run from new ideas. There's certainly no room in the Lilliputian world of literature for myself. Literature to me is a dead art. I'm therefore looking for other arenas in which to express my talents.
