FWIW this wasn't an UFA film, it was a French production financed by the Société générale des films, an outfit that was basically devoted to making what we'd now call ambitious "art films." They also funded Gance's Napoléon. (This was just one of many such, mostly short-lived firms in 1920s France.)Drucker wrote:Not sure specifically about what you are talking about, but it was an Ufa production,
There's a fair bit about the making of Passion on the DFI's Dreyer website, including some on-set photographs.
