Ping Pong Magic
Even in 1994, when this movie was made, the technology of CGI was still pretty impressive. The movie had so many amazing moments where I remember thinking – “How did they do that?” Take this scene, for example, when Forrest had his ping pong tournament.

Ping pong on its own is a difficult thing to film since that little ball is constantly flying and in the air. So technically, it’s a difficult scene to film. But CGI played a large part in those scenes. That ball that you see flying between Forrest and his opponent in the tournament wasn’t real; it was crafted carefully and designed to hit the paddle in order to create the illusion of impressive ping pong skills.
