I'm pretty sure it was Toy Story 2.
God, what a good question. I have no idea. Some of my earliest memories are Jackie Chan films and seeing Deep Impact instead of Armageddon.I'm sure I've seen stuff before that though, possibly Street Fighter or Mortal Kombat? Not sure the chronology of this stuff
I remember my parents taking me and my sis to The Groove Tube ( http://www.imdb.com/title/tt0071583/ ) at the local theater. GOD! I was only 3. After that the next thing I recall was either Star Wars or Saturday Night Fever. I remember standing in line to see Saturday Night Fever, the theater had the Halloween movie poster up and I knew I HAD to see it.
