The Tarkovsky site, linked to in the previous post, is part of a family of sites called Masters of Cinema which themselves have some kind of connection with the cinephile DVD and Blu-Ray series of that name produced by Eureka Video.
The other members are robert-bresson.com and carldreyer.com. I have, and have seen, almost every film produced by Robert Bresson including The Trial of Joan of Arc. Given that the script is based on the transcript of the trial could we say Joan is a co-screenwriter? Perhaps not.
The only Dreyer film I have seen is The Passion of Joan of Arc from 1928. Given its depiction of English soldiers as British Tommies, only 10 years after many of those Tommies died defending France, it is not surprising that it was banned in the UK at the time of release. It disappeared until a print emerged in a Norwegian lunatic asylum, of all places.
