That martial arts sounds hilarious but Leon is obviously right. They could do a parody with it, like Scary Movie 5. But I think this Zombies On A Plane should almost hit the caliber of the original Night of the Living Dead as this will easily create a terrifying atmosphere.
Although I am wondering how big a 747 is, because I think the actors should have a little room to squirm in their seats with what is going on. I have never been on a plane so maybe it is just the right size, but I know there are planes with two floors of passengers in them. Maybe that would work better, or maybe I'm talking about something that I have no clue about. Either way, I can't wait to see this movie.
