Nice move lists. Have watched a good number of them. I am a huge Guillermo Del Toro fan, so few of my picks...

The Orphanage: It changed my perception of horror movies
Pan's Labyrinth: A perfect example of magical realism. Based on spanish civil war.
Julia's Eye

If you are in hindi arts movies, watch Nishant. A damn good movie. Little old, though.

Mr. Nobody (not a foreign film though)
Idiocracy, if you love dark comedies :)
