disaster is basically earthquake with today's technology and movie making. they utilize a green screen and those sort of new special effects tools in the preshow. The subway part is basically the same with the new addition of the video monitors in which The Rock co-stars with you, that's right you! The trailer for a feature length film is being shot and you are a part of it. After the shoot (Subway ride experience) on your way back to the station you get to watch yourself on the screen in the same movie as The Rock.
I love the idea, have rode it, and had a friend actually get me in before it opened since he was one of the head people in charge of installations and other stuff that needed to be done. Well, i liked it, I'm sure you will too if you liked earthquake before
