[EN] This research project is based on the study of the German expressionist art movement, its history and its historical and artistic context, focusing on the graphic art and posters. In this work we will analyze the language of posters and its history in the period covered by the first two decades of the twentieth century, specifying our study in movie posters and the posters in German expressionism. Thus, we will focus our research on which we consider three of the most representative German expressionist cinema films: the Cabinet of Dr. Caligari, Nosferatu and Metropolis; in order both to relate two fundamental aspects of the expressionist movement: graphic art and films, as well as demonstrate the influence of German Expressionism and other Vanguards in the design of the original posters of these three films. In this way, we will also analyze the formal and stylistic components and aspects of these posters such as typography, composition, colour or technique. We will also investigate the different movie posters which were designed for other countries during this period. We will also devote a section to the design of other advertising that was made of these films, such as hand programs, postcards, catalogs, etc. With all this, we will mainly show the influence of expressionism and also other artistic movements, specially the avant-garde, in three fundamental movement movie posters, as well as clear enough some questions about which movie posters are real and which are not. We will also investigate the amount of images that circulate in different media, especially the Internet, where you can confuse movie posters with the designs made for hand programs or ads, and it makes no difference between posters which belonged to the premieres of the films and posters of more current designs, being their authorship totally unclear, going for it to more reliable sources like books or museums. Then, the work will be completed with a personal artistic interpretation of the movie posters, a series of works made with the technique of lithography on the Cabinet of Dr. Caligari, Nosferatu and Metropolis. Finally, we will present three annexes that revolve around the theme: the first one dealing with other poster designs that have been made in more contemporary times (from the 1960s to the present day), the second one complementing the last phase of our task, taking into account our personal interpretation of the posters along with other personal artistic work carried out with other printmaking techniques, and in a final Appendix we will present a digital design of the corporate image of an imaginary Metropolis cinema.
