In the eighties, Hito Steyerl shot a feminist martial arts film on Super-8 stock. Her best friend Andrea Wolf played the lead role, that of a woman warrior dressed in leather and mounted on a motorcycle. The engagement expressed in the formal grammar of exploitation films later became Wolf’s political praxis: She went to fight alongside the PKK in the Kurdish regions between Turkey and northern Iraq, where she was killed in 1998. Now honoured by Kurds as an “immortal revolutionary,” her portrait is carried at demonstrations.
