I don't know if I have a "best movie ever" (if that is the intent of this thread) but I have three "most memorable". The first was when I was around 5'ish and got to take a few classmates with me for my birthday party to see Old Yeller in the early 60"s--quite a treat for us at the time. The second I had to see with a buddy because my girlfriend at the time's parents wouldn't let me take her to a movie with it's rating and that was the debut of Mash. The third was at a theater on Lincolnway near campus in Ames (can't recall the name) in which we prepped heavily for and contributed to the haze that obstructed our view of Fantasia. My family weren't movie goers and I heard most of the reason was because my folks took me to a drive in once as a baby and I filled my diaper several times and my dad claimed he wouldn't go through that again.
