Snakes on the what???

Why does it have to be snakes on a plane and not like snakes in your pants, or in my trailer, or snakes in my apartment?
Like there isn’t enough terror on a plane these days, like terrorists, “exploding water bottles”, shoe bombers and the usual suspect next to you that has not showered in days. Great, now one more thing to fledge a war on…killer snakes. Though I can see the metaphor between the snake the plane and the terrorist. While I have not seen the movie yet I will not dismiss the possibility of ever watching it, though it would be cool if it would be on a plane…
