I love Mira Nair. I admit, I don't know her work well at all. I've only seen Monsoon Wedding (which she directed and produced) and Vanity Fair (which she directed and I saw when it came out and I didn't like it). But my love comes all from Monsoon Wedding. It is one of my favorite movies (and there really aren't really many things I will right out call "favorites," I'm too loving to name names and too indecisive to commit) and I adore it whole heartedly. (Note to self: Put Mira Nair movies to top of Netflix list. Hurry and go see Amelia.)
Here is a quick lesson from Mira Nair, via Third World Girl over at Three Hole Punched, who attended the IFP's Independent Film Conference in New York where Mira Nair spoke (Bobby said, that Sally said, the Jimmy said... Yes, my through the grapevine/telephone game paraphrase lesson from Mira Nair). I looked for a direct quote on the internet for a couple minutes and came up with nothing helpful. So here is the he said/she said version of it. Thanks Third World Girl.
Don't "anthropoligize" or explain too much culturally. If you watch Monsoon Wedding you'll see how much you're thrust into the action. There's no expositional dialogue about why we dress this way or wear this henna, or sing this song. There's no outsider leading you through the action and the work is all the richer and more authentic for it.
