Huh... pretty sad when real life provides a better setup than what imagination in Hollywood can come up with.
Personally I think Plane Dead, a sci-fi zombies on a plane film is the fun outrageous film Snakes on a Plane should be. It has the midnight movie spirit of fun that for me Snakes sorely missed.
Recently renamed Flight of the Living Dead by New Line (should get a DVD release later this year and will play at Fantastic Fest in Austin).
