"History " T.S. Eliot observed is but a contrived corridor- If you are writing a historical screenplay, you do not have to be accurate about the people involved, only to the historical event and result of that event. Add a sequence of events that will personalize the story while leading it to an accurate Historical Result.
It isn't so much the event in History as it is the artist's or writer's reaction to the event. Your effort to get at the greater truth is the goal. One cannot shy from the responsibility to get to and to expose the underlying motivations of those involved in the Historical Event. You may be the proverbial Canary in the Coal Mine. Not everyone understands the ramifications of actions and that there are equal an opposite reactions for every action. If you believe in the Law of Karma which we have previously discussed, you will understand this. To live in denial of it is to live in the world of Delusion or Maya. (Hinduism: Buddhism: the power by which the universe becomes manifest; the illusion or appearance of the phenomenal world.) (Hinduism: the supernatural power wielded by gods and demons to produce illusions.) Not everyone sees or understands things in the same context. What is alarming to you may not even register to another. Hence the times we are living in today should be frighteningly disturbing to you. This just means it is up to you as the writer to write about it, or to write to relieve society of the burden of coping with it or to entertain the masses.
It may be your responsibility to record the event for posterity. In youth you may know the courage and find the strength to "Tempt a God Of Fate," it then is your duty to record what it is that you witnessed. The Golden Rules of the World are absolute. Go seek your Fortune and your Fame but be prepared to accept the responsibility that is yours for your actions.
