The Devil's Trap (Czech: Ďáblova past) is a 1962 Czechoslovak historical film directed by František Vláčil. It is inspired by novel Mlýn na ponorné řece. It is considered the first part of a loose trilogy of historical films by Vláčil. The trilogy aso includes Marketa Lazarová and The Valley of the Bees. The film's main theme is the conflict between religion and science. Religion is represented by a fanatical Jesuit priest, while science is represented by an old miller and his son. Vláčil wanted the film to depict the 16th century as authentically as possible.
