I saw the trailer yesterday and it looked okay.
But I wonder will they vilify him or make him a hero................
He was a commie, so they'll glorify him and cast him as a victim of "McCarthyism."
He was a communist and a subject of the 50s blacklisting
So he will be treated as a hero
He certainly was not evil. He was given a task and the tools and resources to accomplish it. The war was on, and the Germans were already working on an atomic device of their own. There was no question of the necessity. Further, the use of the weapon(s) ultimately saved hundreds of thousands of lives. A reluctant hero perhaps? What happened after the war was largely out of his control. The genie was out of the bottle and other people advanced the science and technology.
