After the publication of "Schindler's Ark" in 1982, Pfefferberg worked to persuade Steven Spielberg to film Keneally's book, using his acquaintance with Spielberg's mother to gain access. Pfefferberg claimed to have called Spielberg's office every week for 11 years. When in 1992 Spielberg agreed to make the film, Pfefferberg worked as an advisor, again making the trip to Poland to show Spielberg the sites; he appears in the film's epilogue and is listed in the end credits as a consultant, under the name Leopold Page. Pfefferberg and his wife were Spielberg's guests on the night "Schindler's List" won seven Academy Awards. In his acceptance speech for best director that night, Spielberg thanked "a survivor named Poldek Pfefferberg ... I owe him such a debt. He has carried the story of Oskar Schindler to all of us."
