Nice interview from Filmmaker Magazine, in which Charlie and Eva HD discuss "How To Shoot A Ghost."
Charlie also lets slip about "shooting in Belgrade for this movie that we're going to make," so it seems like Later The War is still a go and reports of its demise were probably BS. YAY.
Little snippet:
Filmmaker: And then how did it turn into a 23-minute film with high production values and great actors? It’s not like a little experimental sketch.
Kaufman: I think it started as something more modest. We thought we could do it for less and in less time.
HD: I first wrote something, and Charlie was like, “It’s expensive to have actors talking to each other.”
Kaufman: It’s more expensive to shoot sound, yeah.
HD: And so then I was like, well, it could a poem about Athens. And then he was like, “You know what? You shouldn’t worry so much about it.” And then it ended up being more of a combination of those, and we did keep the story of the two ghosts instead of just making a city poem.
Filmmaker: But it’s mostly without sync sound — recorded dialogue — right?
Kaufman: It’s all voiceover. And that felt that felt good to me, that these ghosts would not be chatting with each other. They communicate in a sort of non-verbal way. (Source)
