Okay, checked with my source. Pierre Rissient was going to do a deal with Brocka to distribute a number of his films: Insiang, Tinimbang, Maynila and Tatlo, Dalawa, Isa. The deal fell through and instead of sending back the prints and negatives (which cost money) Rissient deposited them at the BFI, for which we can all be grateful (I'd be more grateful, tho, if they had gotten that distribution deal). Also deposited in the BFI, I don't know if they were part of the deal or not, were Ganito and Itim.
Cinematheque's Bona I don't know what the deal was, but Rissient wasn't involved. Everyone--in Manila at least--thought that was the last remaining copy. The MOMA Bona print we only heard of recently--we have Jojo to thank for the early heads up. That one has English subs, the Cinematheque print has French.
And that's about it, except I'm asking whether Bona in Cinematheque is a print or a print and a negative. What about MOMA Jojo--do they have a negative?
