Lionsgate has commenced a twitter-linked promotion for advanced "Hunger Games" screenings. Here's the link, supposedly. The page isn't opening properly, but that may be a volume thing.
The press releases says "fans can show their support by tweeting a unique hashtag assigned to their closest city to unliock Advance Screening locations. Starting March 1, the top four cities with the most Twitter volume will be announced each day and fans will then be able to enter to win tickets to those locations."
That sounds like the most complicated promo ever, but if your a Katniss nut, you might want to check it out.
