Knowing what we know know about the whole Toy Story franchise, it's hard to believe that, in the beginning, a lot of people had no faith in the whole idea for the movie. In fact, even some major stars who were approached to provide voices for some of the characters declined because they thought the show would bomb.

One of the stars who declined was the multi-talented Billy Crystal. As you'll learn in this video, he was lucky enough to get a chance to provide voice work for Monsters Inc., another Pixar massive hit.

See how the characters changed and other little known facts in this video "Seven things You Didn't Know About Toy Story."

By the way, there is one word that had to be bleeped out, so just be aware of that if you're going to let the kids watch the video.
