CGI in movies dates back all the way to the early '70s, when the film "Westworld" featured CGI in scenes involving the robot Gunslinger. A few decades later, "Toy Story" would become the first film to be entirely rendered in 3D animation. Since then, the use of CGI in film has taken off and never looked back. Gone are the days of special effects that rely on a particular form of physical artistry rather than the use of a computer. As dazzling and convincing as these computer generated effects can be, there are times when I long for the days of practical effects, where on-screen spaceships were nothing more than cleverly shot miniature models and werewolf transformations had to be completed with the use of intricately-built puppets. Today, it seems like practical effects exist in an entirely different world from CGI, and when I think of them, the first name that comes to mind is Tom Savini, the king of prosthetic make-up, the master of horror gore.
