In an essay written two years before his death, Dick described how he learned from his Episcopal priest that an important scene in "Flow My Tears, the Policeman Said" – involving its other main character, the eponymous Police General Felix Buckman, was very similar to a scene in "Acts of the Apostles", a book of the New Testament. Film director Richard Linklater discusses this novel in his film "Waking Life", which begins with a scene reminiscent of another Dick novel, "Time Out of Joint".
