Just to add some flavor
Metropolis - The Great Grandfather of great movies: Social Commentary & Special Effects plus a vision of the future through the eyes of people in the 1920's (its silent, but background music is dubbed in). Also watch for the '80s re-release with music by Queen and others.
Lawrance of Arabia - see it in letter box format.
Lonesome Dove - Ok, so I like long movies.
Dances with Wolves - Ok, so I like long movies. Get a directors cuts version
Better Off Dead - with John Kuzak(?) Best part is when his mom's new dish crawls off the plate: "its got raisins in it...you like raisins."
(and who ever though french girls were such great mechanics?)
Repo Man - how many generic products and rock musicians can you find?
The Princess Bride - wished I could have seen it in the theater. (And this one will win points for you with your wife or girl-friends)
(And don't tell your wife about your girlfriends
Henry V - best movie of a Shakespear play I have seen.
