In Inglourious Basterds when Lt. Archie Hicox is briefed by Gen. Fenech and Winston Churchill, his qualities as movie expert are put to a little test when he is asked by Churchill about Joseph Goebbels in his role as a movie producer:
Churchill: You say he wants to take on the Jews at their own game? Compared to say Louis B. Mayer...how's he doing?
Hicox: Quite well, actually. Since Goebbels has taken over, film attendance has steadily risen in Germany over the last eight years. But Louis B.Mayer wouldn't be Goebbels proper opposite number. I believe Goebbels see's himself closer to David O. Selznick.
After which Chuchill agrees to brief Hicox for the upcoming operation. So there has to be some truth in Hicox's explanations, a truth that Churchill as a (I suppose) non-expert understood. But I for myself, being not too well-versed in Hollywood history, am not sure if this was a correct comparison or not. So in which way was Joseph Goebbels in his role as a movie producer more similar to David O. Selznick than to Louis B. Mayer?
(While it may also just have been a rather arbitrary comparison not supposed to be made much sense of, with Tarantino's and the whole movie's general obsession with the movies, I bet there to be some truth or reference in this statement.)
