You can always count on F.W. Murnau to deliver the goods. Nosferatu—though a blatant act of plagiarism—changed the landscape of horror films forever, bringing in the mood and character that allowed the genre to reach new heights in the ensuing decades.
The level of refinement in this film—one made in 1921, almost a century ago—is astonishing. The double exposure used to give transparency to the phantoms is artfully done, certainly, and the acting is more nuanced and intuitive here than in most films released this decade.
Häxan is one wickedly innovative silent film, and I mean that in a good way.
