Since the mid-1970s, American avant-garde filmmaker and artist Leslie Thornton (born 1951) has produced an influential body of work in film and video. Thornton's early encounters with experimental, structuralist, and cinéma vérité traditions fueled her iconoclastic take on the moving image and gave shape to her practice of weaving together her own footage and voice with archival film and audio. In part through her forceful and dynamic use of sound, Thornton exposes the limits of language and vision in her works, while acknowledging the ways that language and vision nevertheless remain central to scientific discourse and narrative in general. Her work consistently interrogates modes of representation and the violence of looking, pushing beyond critiques of the gaze to consider biases in perception, or the way voice and sound can undermine an otherwise dominant visual narrative.
