Movies with great impact on me:
1. Untouchable - must see
2. Gattaca - are we going there?
3. 1984 - must see
4. Idiocracy - initially looks like joke/stupid movie, but it's more real then we may want to agree
5. Life of others (made in Ge)
6. Amelie Poulain (made in Fr)
7. Turtles can fly (made in Ir)
8. Stalker - the russian original (3 parts) (made in Ru)
9. Metropolis
Other good movies:
Lost Horizon
The Bucket List
The Truman Show
Solaris 1972
Enemy at the Gates

Tips for good movies in general: take countries one by one and search best ever movies from that country.
