Hmmm, I don't know. Were you on the main Bollywhat forum page when you typed pushpak in the search box? When I do it there, I get a list of different threads throughout the forum that mention it, and the filmfare thread is second in the list. Maybe you were in one of the subforums when you searched?
ETA: Now I'm wondering why I started that Pushpak thread in Filmfare and not in Beyond Bollywood. It's a silent film, so it doesn't have a language, but it was filmed in Bangalore by a Telugu director and had a Kannada producer. And I think the date should be 1987 instead of 1988. Maybe it should be moved to Beyond Bollywood?
Tried it again and it's working now. Wierd.
Interesting question about where exactly to place it. I don't consider this a BW film, that is for sure, not so much because of language --or lack of-- but because of the style of filmaking. To be honest, I think this one is in a league of its own!
