I've been looking through the archives recently, and I saw that this video was never reuploaded. Thankfully, these days, it's
on youtube. The transformation scene is at the end of the trailer. She (He? It?) dies almost immediately after that scene.
The full movie is actually on youtube too, and I might watch it later since I like Leslie Nielson movies, but I didn't see anything that would suggest that there'd be any more TF content.
