In 2016, the Noordbrabants Museum in the Dutch city of Den Bosch held a special exhibition devoted to the work of Hieronymus Bosch, who died 500 years ago after spending his entire life in that city. This documentary follows a team of art historians as they crisscross the globe in preparation for the exhibition, trying to unravel the secrets of Bosch’s fantastical and disturbing art. The film is “no mere appreciation piece, nor an advertisement for the sanctity or edifying calm of the museum space. Instead, it . . . places curatorial efforts into fascinating light” (Clayton Dillard, Slant).
