Getrud Koch has long been a keen observer and critic of cinema. She is well-known beyond the specialist public as a film scholar and theorist. To celebrate her birthday, colleagues and co-workers have organized a conference on film studies that will take place on April 24 and 25 at the ICI Berlin. The start will be made with a celebration at Arsenal during which Vivian Ostrovsky, Ulrike Ottinger and Tom Tykwer, among others, will present clips, films and talks for Gertrud Koch. The main focus is on the interactions between the individual "I" and the social "we" in the mass medium of film, something which utopias in art and politics have been addressing time and again since the 1920s. Gertrud Koch is Professor at the Department of Film Studies of FU Berlin and since 2005 Member of the Advisory Board of Arsenal – Institut für Film und Videokunst. (April 23)
