Hi. I happen to like, and have recently seen "Twister" for about the fifth time. lol It's kind of like a cult-type movie to me.

I did a lot of searching for answers online to your questions. While I did not find them, it might be possible to get the information you want if you contact the production company and/or the movie company(ies) that made and/or released and distributed "Twister," they might be able to give you the information you are looking for.

It is a Warner Brothers film. If you go to the Warner Brothers web site, type in "Twister" in the little spot where it says search in the upper right hand corner, a small part of the movie will play on the little screen. While you watch this, keep an eye out for the name of a production company (which is not Warner Brothers). Perhaps contact that company, in addition to Warner Brothers.

Gook luck and happy hunting.
