So you can definitely portray historical figures without permission, right?. For example no one is getting permission from Hitler’s estate for WW2 movies AFAIK.

So you can definitely portray historical figures without permission, right?. For example no one is getting permission from Hitler’s estate for WW2 movies AFAIK. If you have someone playing Hitler in an alternate reality where he was a bartender, is that illegal today? Can’t you do the same with an actor? Or do you actually need permission to portray historical figures, and Hitler or Napoleon etc are just special cases because they don’t have estates to be asked?
