Show up at the box office. They don't do any other way. It is a really big theater, the old style, i have never seen them sell out.
Also, it is a cash only venue.
It's a Wonderful Life is on Christmas Eve, not the 14th. Sales start at the box office during regular business hours and are $ 10 cash, so no debit cards. They said that they expect to sell out, so buy your tickets early.
