Flash movies that "pop out" of their boundaries

I am working on a project in which I want a portion of a flash movie to pop out of the boundaries of a flash movie. I’ve seen this done in ads at the top of imdb.com when they had banner ads, and many other places. When you mouse over the flash movie, it increases inside, covering up some of the content of the page and then animating back into its original place when you mouse out of the movie.

I’m sure there is a tutorial or example on how to do this out there but I cant find it.

Can someone point me in the right direction? Am I even making sense?
