One of the most influential directors in cinema, Carl Theodor Dreyer had a complicated relationship with film. Somewhat prolific during the silent era, he made a number of iconic films including Vampyr. Having experienced some commercial and critical failures during that transition between silent and talkie, Dreyer’s output became more spare. He would still end up making a number of essential pieces of cinema, such as Day of Wrath and Ordet, but he was notoriously difficult to work with, and found the process of film-making and dealing with the bankrollers hard enough himself. Much like Welles as an example, Dreyer was a boundary pusher. He was a director who would defy the rules and expected nothing less than complete control on a film. He would use cinematic techniques that were virtually unheard of in his earlier career, and stylistic choices that were decades ahead of their time. Subsequently of course, many of his films still hold up very well by today’s aesthetics.
