In 2004 the Dutch film company Zeppers Film & TV, in a coproduction with NPS, released a 90-minute documentary by Dutch director Jos de Putter entitled "Alias Kurban Said". The film examines the disagreements over the novel's authorship. "Variety" called it a "Magnificent historical whodunit, wherein crumbling photographs, yellowing documents, and forgotten reels of 35 mm film are invested with tremendous evocative power." The film shows documentary evidence that Abraham Nussimbaum was a proprietor of oil wells sold to the Nobel firm in 1913. The film was an official selection of the Tribeca Film Festival, the International Film Festival, Rotterdam, and the 2005 Netherlands Film Festival. Its music won the prize for Best Music at the Netherlands Film Festival.
