This website provides a research hub for those interested in early film theory. It serves as a supplement to the sourcebook The Promise of Cinema: German Film Theory, 1907-1933, which brings together hundreds of texts by theorists, intellectuals, and filmmakers, documenting the early twentieth century’s efforts to assimilate modernity’s most powerful medium. Users will find a collation of German film-theoretical publications before 1933, links to films as well as suggestions for researching and teaching Weimar cinema. There are also illustrations of relevant film-technological devices and links to further online resources. In addition, the site features additional texts in translation and original essays by scholars that engage with material from the book, as well as a creative rubric that explores media-theoretical concepts and constellations. We welcome contributions from users.
