en PortalulTauTV. Johann Lurf‘s film Endeavour slides between documentary, avant-garde film, and science-fiction. This highly singular combination of materials and techniques gives the viewer of Endeavour a feeling of flight, as the film continually evades the gravity of genres and definitive definitions. Lurf uses NASA footage from a day and a night launch of the space-shuttle that follows the booster rockets from take-off to splashdown.
