I’ve gotten more than one phone call today from people at New Line asking me to clarify that this trailer is not the official teaser trailer for the film, it was put online merely for the songwriting contest at Tagworld. The CG is not representative of how the snakes will look in the final cut. The OFFICIAL official teaser trailer will apparently be coming out in about a month. - the guy who runs SOAB
And if you haven't seen it yet, here's the official movie site: http://www.snakesonaplanemovie.com/
Not much to do yet.
