Filmforum, Municipal cinema in Duisburg, Germany

The filmforum is a cinema in Duisburg dedicated to film and documentary programming. Its building features a distinctive facade and houses a comprehensive archive with thousands of film copies, historical posters, and documentation materials for research.

The cinema began as a project of a local adult education institution in 1959 and officially opened to the public in 1970. It has since developed into an important center for film culture in the region.

The name "filmforum" dates from 1959, when the Duisburg Volkshochschule began screening demanding films under that programme title; its success led to a permanent municipal cinema. Since 1977 the venue has been tied to the Duisburger Filmwoche, and in July and August it runs an open-air summer cinema in the Gießhalle of the Landschaftspark Duisburg-Nord.

The cinema sits at Dellplatz in the Dellviertel district, in a building that housed a cinema since the 1940s. The venue is not wheelchair accessible. The filmforum archive, one of the largest in North Rhine-Westphalia, can be consulted for film-historical research.

Since 1996 the filmforum has held its summer open-air cinema in the Gießhalle of the Landschaftspark Duisburg-Nord, a former smelting plant. Diebels sponsored it until 2007, when Stadtwerke Duisburg took over the naming. In 2016 it sold 44,125 tickets, its highest figure so far.
