Most "intellectually" engaging movie...

[Roland1919]

I, like many, have watched thousands of movies but there are a few that come to me as being intellectuall. You know the ones that really make you think - doesn't matter "how", they just make you think. Remember rational not emotional. Some of my personal favorites include: Solaris; Magnolia (for both rational and emotional intellect); Ghost in the Shell always leaves me agog. How many times have i hit reverse scan on that one? Also love 2001 Sapce Odyssey for the same reasons, Donnie Darko at times. I know everyone loves Blade Runner for this reason though I must say I'm not a big fan. I will watch it again because someone pointed out that Ford's character may be a replica. Interesting. Wall Street may be at the top because it may me think in ways I rarely do and at the same time taught me of a subject I knew little of. I can go on and on but I'd like to hear some opinions...
