I am a movie director and I just received the following movie plot. Could you help me answer this question? If not, let me know by writing "Not answerable". Plot title: Nasser Asphalt Movie plot: The young journalist Bachmann (Horst Buchholz) is released from prison by the intervention of Cesar Boyd (Martin Held), a respected and prosperous journalist who hires him as his assistant. Bachmann had been in jail for his attempt to interview war criminals at Spandau prison. Bachmann works for Boyd who acts as his mentor, however, Bachmann's stories are published under Boyd's name. Bettina (Maria Perschy), the daughter of a friend comes to study in Berlin and will stay at Boyd. Both Bachmann who picks her up at the airport and Boyd develop an interest in the young woman. In the commotion, a story that has to go out to a Paris newspaper is not prepared, and Boyd, after listening to a tale from his chauffeur Jupp (Gert Frobe), in the last minute makes up a story of five German soldiers who have lived in a supply bunker in Poland for six years where they had gotten trapped when it was exploded at the end of the war. There is one survivor, now blind, who was brought to a hospital. The story becomes an international sensation and people want to know more. Journalists are sent to Poland to investigate. The Russians suspect the story to be a ruse to send spies. Pressure is put on the Polish government to release the blind soldier. In Germany, widows believe the blind soldier may be their missing husband. Bachmann who initially thought that Boyd had reliable sources for his story, soon recognizes that it is all a big lie. He breaks with his mentor, and tries to warn the public about the hoax. He convinces Bettina of Boyd's lies, and both of them leave him to start a new beginning. My question: Who is Greg's idol?
The answer to this question is:
Cesar Boyd
