In the poignant documentary "Skin of Glass," director Denise Zmekhol embarks on a deeply personal journey through time and memory, tracing the luminous legacy of her father, the modernist architect Roger Zmekhol. Decades after his sudden death, she returns to Brazil, where his iconic glass-paneled buildings once symbolized a gleaming future. Through intimate conversations with figures like activist Eduardo Suplicy and architect Paulo Mendes da Rocha, the film explores how these structures, now neglected and mirrored by a landscape of social inequality, reflect a nation's fractured dreams. Blending evocative archival footage with contemporary observation, the film weaves a lyrical meditation on loss, idealism, and the fragile transparency of history itself, questioning what remains when the future we build begins to crack.
