I've read that the original plans for Trey and Matt was to do a scene-by-scene re-shoot (actually a CO-shoot) of "The Day After Tomorrow" with puppets (a film they had access to a copy of the script before production began), and to release it on the very same day as the live action version, labeling it the "puppet version". Unfortunally they would have some legal problems doing that, and they decided to do an original movie instead.
