My favorite Spanish language film is a kinda old one -- "Like Water for Chocolate". I loved that one.
I absolutely LOVE LOVE LOVE films from New Zealand, specifically about the Maori culture:
Whale Rider
Once Were Warriors and its sequel What Becomes of the Broken Hearted
The Maori Merchant of Venice (the Maori version of the Shakespeare play)
I remember going to my Indigenous Politics class one day and I almost fainted when I saw Rena Owen and Temuera Morrison (the lead actor and actress from Once Were Warriors) sitting in front. They came to lecture on the Maori in film that day.
