Both Krauses were Jews, but not particularly observant, said filmmaker Steven Pressman, who created the documentary.
"Let me describe the Krauses this way," Mr. Pressman told The Washington Times in a telephone interview. "Gilbert, in particular, came from a long-standing German-Jewish family, professional class, upper middle income, not wealthy, but comfortable. Almost all of them were very secular Jews, they were not religious Jews, [but] they were part of that crowd and community. They were not religious, but [they were] very social-minded."
