How they did Forrest Gump

As we get deeper and deeper into after effects with this class I've really enjoyed figuring out how these special effects or movie magic actually worked. One of my favorite movies form when I was younger, Forrest Gump, was one of the films I consistently was stumped by. Between how they hid Lt. Dans legs, Forrest meeting John Lennon, Nixon, and JFK there was a lot to wonder about. But now that we're getting into rotoscoping and splicing ourselves into films it's becoming clearer to me. To confirm some of these curiosities, here is a site explaining each of the special effects in the film and how they pulled them off.
