Movies are the most powerful tools of propaganda the world has ever known. They have the ability to mold public opinion, in ways both overt and covert, on every topic from fashion to war.
Think about it. America has never won a modern war without Hollywood’s support. And when Hollywood turns against a war, as it did with Vietnam, Iraq and Afghanistan, America loses the will to fight and ignobly surrenders.
The same thing happens when movies retell history.
