There was a gap of eleven years between this film and Dreyer's last feature, being Vampyr in 1932.
Though the film is outwardly a chronicle of a religious witch-hunt, it contained many subtler comparisons to the behavior of the Nazis (torture and questioning) and Carl Theodor Dreyer fled Denmark for Sweden where he remained until the war was over.
This film is part of the Criterion Collection, spine #125.
