For four decades, the reputed American artist Leslie Thornton (1951) has created a complex and penetrating body of films and videos, characterised by constant displacement or by their interstitial positioning. Some traits of a work that resists comfortable classifications are the questioning of borders and the overlapping between resources and supports; the continual exploration of the possibilities afforded by changing technology; critical investigation into notions of narration and representation; interrogation of the closed or completed work and, consequently, postponement of its semiotic closure. In fact, many of her pieces are conceived as series of episodes in constant development and have been re-made and re-structured over the decades, as is the case of the classic Peggy and Fred in Hell (1984-2015) —a milestone in contemporary experimental cinema— or The Great Invisible (2002-), both presented here in their most recent version.
