Movies today are filled with images we didn't think were possible. That's because they aren't. They are the result of CGI. Computer Generated Imagery. Some films are full of CGI. It's one of the complaints many people have about the Star Wars prequel trilogy. Set were completely replaced by green screens and the use of CGI. I think the best use of CGI is in a movie where it is blended in and used WITH real sets and actors. As amazing as the technology gets, you just can't beat real sets and actors.

The real fun with CGI is seeing a scene of a movie before the imagery is all finished. What does the Hulk look like before CGI? What about Iron Man and Alice in Wonderland? Check out a gallery of famous movies scenes BEFORE the CGI was added in!
