Schindler's List is a 1993 epic drama film directed and co-produced by Steven Spielberg and scripted by Steven Zaillian. It is based on the novel Schindler's Ark by Thomas Keneally, an Australian novelist. The film tells the story of Oskar Schindler, a German businessman who saved the lives of more than a thousand mostly Polish-Jewish refugees during the Holocaust by employing them in his factories. It stars Liam Neeson as Schindler, Ralph Fiennes as Schutzstaffel (SS)-officer Amon Gth, and Ben Kingsley as Schindler's Jewish accountant Itzhak Stern. John Williams composed the score. Ideas for a film about the Schindlerjuden were proposed as early as 1963. Poldek Pfefferberg, one of the Schindlerjuden, made it his life's mission to tell the story of Schindler. When executive Sid Sheinberg sent a review of Schindler's Ark to Spielberg, the director was fascinated by the book. He eventually expressed enough interest for Universal Pictures to buy the rights to the novel.
