"The truth is, America's commitment to free speech is dwarfed by our commitment to capitalism. Seth Rogen can stand in his house and say anything he wants about Kim Jong-un – but Sony has the choice to fund him, and even if it agrees, AMC can still pull the plug. The corporation, not the individual, has always had the power to decide what movie is a thoughtcrime. We're just only now visibly seeing the suits flex their clout. Despite everything, Pascal at least had the courage to greenlight a comedy about a sitting dictator. Will she be the last studio boss who can make that claim?"
I wouldn't be surprised if it turns out that the hacks or threats weren't conducted by NK, or by NK alone. This movie is in fact a threat to a particular regime in NK, but it's also a blanket threat against all totalitarian regimes (and corporations), and there are plenty that would be upset about that.
I've been scouring Hollywood for movies that appeal to mass social, political, or economic change that don't portray the instigators as crazed violent goonies. There are none in recent memory. The ones that do strike a chord become wild blockbuster hits and their motifs enter our collective consciousness as light-sabres or guy fawkes masks, but they are the rare ones. You don't find much of them in Hollywood because Hollywood does not instigate change.
