Yes - a real movie. To quote Samuel L. Jackson
"They had already changed the title when I got to Canada to start shooting. I let it go for a while. Then one day all the producers were standing there, and I'm saying, "So are you seriously going to leave this name like this?" And they're going, "Yeah, we don't want to give too much away to the audience." I'm like, "Yeah you do. That's the way you get them in here. Nobody wants to see Pacific Air Flight 121. People want to see Snakes on a Plane." When I picked up the script and I saw the title, I didn't even read it and I said, "I want to do it." You know, before I opened the first page, Snakes on a Plane. If this is what I think it is, I want to be in this. I want to be on a plane full of poisonous snakes. And I want to see other people on a plane full of poisonous snakes. You say Snakes on a Plane, people who don't like snakes are intrigued. The people who don't like to fly are intrigued. The people who don't like both are totally terrified now. People who just like seeing mayhem are ready for that. They want to see, you know, people enclosed in a big tin tube getting attacked by poisonous snakes. Come on! What could be more exciting than that, you know? What do you do? What do you do until the plane lands? Come on, Snakes on a Plane, that's the title."
