Best of Enemies: Buckley vs. Vidal background creation

The production of the film was inspired by a pirated CD accidentally discovered by Robert Gordon. When the two directors decided to make the film, they didn't want to make the film from their own point of view. They wanted to make a film about "debate". In order to obtain a wealth of background information, the director did a lot of preliminary research work, and bought all relevant materials from the ABC, and found many precious shots in it. The rhythm of the film is basically determined from the draft stage. In the four years of pre-production, the director listened to all possible useful materials, and finally found out the music material that best matched the rhythm of the film among the waltz and ballet   .
