Lotus reads has reviewed an Indian film all about spices (The Mistress of Spices), but she says it is not a recommended film.
Here's a better one about spices, Greek this time. Called Politiki Kouzina or A Touch of Spice in English, it is about a Greek family living in Constantinople (as the Greeks still call Istanbul), where the Grandfather keeps a spice shop. The shop serves Greeks and Turks alike. The grandson becomes a good cook even when he is only 10, and much of the film revolves around family cooking and which spices to use. The boy has a friend who is a Turkish girl. But the family is forced to leave Istanbul for Athens in the late 50s, leaving the grandfather behind.
Eventually the grown son returns to Istanbul and meets the grown Turkish girl who now has a husband and a daughter. I won't spoil the end for you. It's a sad story about exile but vivid about life and food in Constantinople. It's was very popular in Greece while we were there.
There's a DVD. It has English subtitles when they spoke Greek but later in the film the Turkish dialogue is rendered in English without subtitles.
