ANDREW BUJALSKI, interviewed by Max Cea in "Nothing Bogus":

"I've been very lucky my whole career to work with Matthias Grunsky, who is a great DP and extremely competent in all manners technical. But I hope there's a trust there that I'm going to keep making his job hard for him. And every time we find new ways to make it hard. Always leaving room for the performances to lead, which is not how it always works on a movie set."

EDGAR REITZ, in "Leibniz – Das Filmbuch":

"I hadn't known Matthias Grunsky at all before. The first thing I noticed when we met was his incredible capacity for enthusiasm. From the very first moment, Matthias let himself be completely swept up by the material and the story. We experimented together. Never before had I experimented so much with a cinematographer before principal photography."
