Oppenheimer was quest at Helsinki International Film Festival in which I saw the film. He held before and after screening Q&A's (yes, it's okay to laugh at it, people in Indonesia laughed the hardest in fact ) and after that he got ambushed outside theatre for almost hour by adoring viewers. I went to speak with him and editor after most of the masses had disappeared so it was only me, my friend (not Oz) ando ne other guy so it was really nice privateish little chat.
As for editor, he happend to be in Helsinki because he's also editor of Pirjo Honkasalo's first fiction film in ages, Betoniyö/Concrete Night and the film premiered at HIFF during the same day (in fact only reason I didn't get to see film then was screening overlap with Act of Killing screening I had bought tickets for).
Anyway, Betoniyö - going by reviews and footage I've seen- seems godly as expected from Honkasalo so I might be even more hype for it than Gravity. The problem is it only had short stint in my hometown and I missed it because of being too busy with my uni studies so I probably have to wait for DVD/BD release. :(
