This documentary about architect Antoni Gaudi’s unfinished magnum opus, the Sagrada Familia, traces the improbable history of the basilica, first begun in 1882 and still just over half complete. Gaudi’s Gothic and Art Nouveau-influenced 18-steeple structure originally depended on erratic contributions from the faithful, but today is well-financed by tourist tickets. Stefan Haupt’s narration focuses on the people who have carried on Gaudi’s legacy through the decades, with various creative and spiritual agendas. The main contrast in approach can be seen between two of the church’s façade sculptors: Japanese-born Etsuro Sotoo, a former Zen Buddhist who converted to Roman Catholicism out of his devotion to Gaudi, is committed to understanding Gaudi and his vision of nature. In contrast, Catalan sculptor, Josep Maria Subirachs, whose angular modernist sculptures contrast with Gaudi’s curvilinear forms, chooses to honour the architect’s achievement with his own originality.
