The film and the book are both faithful to the historical facts and the testimonies of the survivors, but they also differ in some aspects. The film focuses more on the visual and emotional impact of the events, using black and white cinematography, music, and symbolism to create a realistic and immersive atmosphere. The film also omits some of the subplots and characters from the book, such as Schindler’s wife Emilie, his mistress Ingrid, and his Jewish friend Poldek Pfefferberg, who inspired Keneally to write the book.

The book, on the other hand, provides more background and context to the story, explaining the historical and political situation in Europe, the origins and motivations of Schindler, and the fate of the Schindlerjuden after the war. The book also explores the moral and ethical dilemmas that Schindler faced, as well as the complexity and ambiguity of his character. The book is written in a documentary style, with a lot of details and quotations from various sources.
