...the upcoming movie Snakes on a Plane is simply a marketing experiment. As far as I can tell, the studio decided to bring in a big-name star and then come up with the most absurd possible plot and see if the public would eat it up. Well, the buzz for the movie is incredible so far (at least in terms of being talked about, especially on the internet), so it looks like New Line might be onto something. My favorite part of the Wikipedia entry for the movie is the fact that after wrapping principal photography, scenes were re-shot to ensure an R rating.
If the movie is as successful as it appears like it will be, look for other movies like it to come out very soon thereafter (in fact they are probably already in production...maybe Sharks on a muthafuckin' Boat?). I am still not sure, however, if I will be seeing the movie.
