I used to maintain an Access database of every Indian movie I'd ever seen or felt some kind of interest in-on a good day I actually still manage to remember to update it with stuff I've seen.
Viewing wishlist, off the top of my head, with a bit of prompting from wikipedia:
Oldies: CID, Chunaoti, Mard, Sachcha Jhootha, Suhaag (Manmohan Desai movie), Bhumika, Karate (w/Mithun), Ashanti, Prem Pratigyaa, Biwi-O-Biwi, Humjoli, Caravan, Gair Kanooni, Khoobsurat, the Dharmendra Alibaba, Dharam-Veer, Teri Meherbaniyan
90s: Khudah Gawah, Dil, Maha-Sangram, Chhote Sarkar, Sangeet, Hum Aapke Hain Koun, Anjaam, Mrityudand, Aarzoo, Itihaas, Baadshah, Kaun Sachcha Kaun Jhootha, Angaarey, maybe Maiden-E-Jung and Sapoot
00s: Kal Ho Na Ho, Chak De India, Black, Khakee, Aankhen, Bhagam Bhag, Welcome, Omkara, Main Hoon Na, Ek Vivah Aisa Bhi
2010 to present: De Dana Dan, Talaash (with Aamir), Lootera, Chashme Buddoor remake, Chalo Dilli, Go Goa Gone, Sahib Biwi Aur Gangster Returns, Phata Poster Nikla Hero, Boss, Bol Bachchan, Zindagi Na Milegi Dobaara, Chennai Express, Commando, Queen, Gulaab Gang, Dedh Ishqiya
South Indian films: Amen, Maatraan, Arrambam, Mankatha, Baadshah (NTR Jr), Mr. Perfect, Paramasivan, Thalaivaa, Manichitrathazhu, Chandee, Pavitra, Paava Manippu
Too many to list here, but there's a few old cheesefest movies I'd really like to get my hands on: Adventures of Robinhood and Bandits, Lady Robinhood, and Rocket Tarzan(!!). Somebody really needs to release a box-set of all BJ Patel's classics. Oh, and Hunterwali, starring the legendary Fearless Nadia.
