So since junior high, I've seen this movie a million times, but I've never watched it from the perspective I did the other day, which was to decipher why this movie is on the list. I think possibly the biggest reason is Tom Hanks's acting. He does such an amazing job as Forrest, believably playing a mentally challenged adult and keeping the role light, making Forrest innocently hilarious. It's also very well-written and about every ten minutes of the movie, you'll hear a quote that anyone could identify as a line from Forrest Gump.
I never realized it before, but the special effects in this movie are incredible. Forrest really looks like he met those Presidents and attended basically every historic event of the '60s and '70s. And while it's not a reason to be on the list, soundtracks can very much affect how much I personally enjoy a movie, and The Forrest Gump soundtrack was one of the few tapes my parents had in our car growing up so I knew and loved every song before I even saw the movie. ("Love Her Madly" is still my favorite Doors song.)
Overall, a beautiful, moving story that's so well-acted it certainly earns its spot on the list.
Big Names: Tom Hanks, Robin Wright (Buttercup from The Princess Bride), Sally Field, Haley Joel Osment (this is his second appearance in the list so far... pretty impressive for a little kid)
