Häxan is a curious and enjoyable Swedish/Danish silent movie. It is a documentary horror exploring witchcraft and superstition from the Middle Ages onwards with numerous dramatised vignettes featuring witches, black magic and various devilment.
Some parts of the film are tinted which adds to the creepiness and/or fun especially when the tint is red.
A controversial film, scenes of nudity and torture helped it be banned in several countries. The film is full of weirdness and the forbidden, it's a lot of fun. The early part of the film, which is mostly documentary, can drag a bit though.
