Every movie made by the production company founded by Ismail Merchant and James Ivory in 1961.
Most of these films were produced by Ismail Merchant and directed by James Ivory, and many were written by Ruth Prawer Jhabvala. (Merchant directed some films of his own, and occasionally the group would produce films by other writers and directors.)
Gonna try to watch all of these.
