Snakes on a Plane is probably the only movie ever given an award by Wired for "the worst film of 2006", based on just the title and the premise of the movie.
That same title and premise also made SOAP a jolly good internet meme: it sparked tons of fan-made art, parodies, and all-round buzz.
To counter Wired, some people at IMDB are even trying to vote it top 250 movies of all time without seeing the movie.
So good is the buzz that Newline Cinema decided to go back and re-shoot the movie to take the movie from a PG-13 to an R-rating!
