Art has always been seen as a form of expressing emotions and ideas; an artist creates an idea and models it with culturally known objects and shapes to send an encrypted message. Over time, both the ideas and the materials used separate art into different periods and movements. Between the late 1940s and the late 1950s, two artistic and cultural movements emerged from each other. The first, Lettrism, aspired to rewrite all human knowledge. From it another movement was born, Situationism. It was an anti-art movement that sought the Cultural Revolution. Both of these movements belong to a broad and difficult to define movement of experimentation, a movement whose field is infinite. Many different people create experimental films for a variety of reasons. Some wish to express their unconventional views. But most of them have an enthusiasm for the medium itself. They want to explore what perspectives the medium has and want to open up new opportunities to create and explore, as well as educate. The experimental director, unlike traditional directors, wishes to break away from orthodox notions. Overall appreciation is not the goal experimental filmmakers would seek. Experimenters usually work on the film alone or with a small group, without a large budget. They intend to challenge traditional ideas. And with the intention of doing so, Lettrism seeks to narrow the distance between poetry and people's lives, while Situationism seeks to transform the world into one that exists in a constant state of novelty. Both of these avant-garde movements come from similar sources and have similar foundations. However, they have different intentions towards the world of art and culture and these movements...... middle of paper ......p from the world in which they live, a world of separation and they indicate themselves with their own reality. Art is delivered into the hands of society, as in a movement it is suggested: fix what is real, live as one creates and create as one lives; in others – abandoning the ideas proposed by the media and taking the leadership of life into our own hands.
