I have a some recommendations from vintage bollywood. As an aside, i'm having genuine fun finding the english titles for the indian films. if i were given a list with those and asked if i'd seen any, i'd have said no 

Here they are:

Towards the Light (1944), Two Acres of Land (1953), Madhumati (195 & Bandini (1963) - Bimal Roy

Andaz (Beau Monde/A Matter of Style) 1949 - Mehboob Khan

The Division (1953) - Kamal Amrohi

Two Eyes, Twelve Hands 91957) - V. Shantaram

Master, Mistress and Slave (1962) - Abrar Alvi (Guru Dutt plays the master)

Fire (194 & My Name Is Joker (1970) - Raj Kapoor (the second film is deeply flawed, but a pathbreaking one for bollywood, nevertheless)

Guide (1965) - Vijay Anand

The Third Oath (1966), Experience (1971), Discovery (1973) - Basu Bhattacharya

Flames (1975) - Ramesh Sippy (better known as "Sholay" worldwide, this is kitschy and over-the-top, but a milestone in Indian mainstream cinema)

Just realised that i'd forgotten to mention two lovely films in my "also" list following the top ten: "What Makes Albert Pinto Angry?" & "Salim Langde Pe Mat Ro" (can't find the English title) by Saeed Mirza.

especially @ john
Seek out this film called "Umrao Jaan" by Muzaffar Ali. I think you'll love it.
