According to Wikitoolazytolookfurtherpedia, the change took less than $1 M (on a production budget of $75 M) as they reshot a few scenes and changed all the Chinese insignia to North Korean in digital post-production. This alone reminds me so much of the event in Nineteen eighty-four where Winston Smith is at a Hate Week Rally and a speaker changes the enemy from Eurasia to Eastasia mid-speech - within a few minutes, after the posters and banners that had been put up by the agents of Goldstein have all been torn down, the crowd is back hating, just at a different enemy - and poor Winston has a week of overtime work and revision ahead of him as they have to prove that Eastasia has always been the enemy. Except that Winston is not manufacturing lies for ideological and political consistency, he is doing it so his employer does not lose market share.

Hah. You are awesome.

Seriously, I can't wait to see it. I think I'm going to see it with a Maoist. Hah. It looks so shitty.
