Tonight the World draws from a cross-section of dream diaries kept by Martin’s grandmother, Susi Stiassni, who fled the imminent Nazi occupation of Czechoslavakia in 1938. Through five chapters, the film links as many dreams sited in Susi’s childhood home, Villa Stiassni, a modernist mansion built by Susi’s parents, who were prominent Jewish textile manufacturers in the industrial hub of Brno. Conjured in Susi’s imagination from her middle-age onwards, in the context of psychoanalysis, the dream diaries as a whole span 40 years and 40,000 dreams, but Martin’s selection focuses tightly on dreams about intruders within the Villa, recreating a narrative of threat and escape that parallels Susi’s lived experience. Retracing the legacy of her grandmother’s emotional history, Martin considers the unconscious underpinnings of intergenerational trauma, loss and resilience.
