The third The Hobbit: An Unexpected Journey TV spot packs an awful lot of action into just 30 seconds, plus two reminders to buy your tickets (which go on sale this Wednesday) in advance. Also going on sale this Wednesday are tickets for the theatrical marathon of the extended edition of The Lord of the Rings, taking place on December 8th and 9th. It’s sure to sell out, so buy your tickets early. You should also probably start building up your tolerance for sitting in an uncomfortable chair for four or so hours at a time. A numb butt is the enemy of a positive movie marathon experience. Trust me.
