Why is this happening? After extensive Googling, I still don't know. The only reference to similar editing comes from a post on Shanghaiist in May reporting identical censorship in China. It's strange because Rourke's character isn't political or ideological & no scenes or dialogue appear to have been changed - just the words "Russia" or "Russian."
Speculation on internet message boards is that somehow Cox & Comcast acquired the censored version & are now selling it without having watched it (and continuing to sell it despite customer complaints). I spoke to a Cox customer service representative this morning who was unaware of the problem & refused my request for a refund. (Update 10/12: Cox called me back today to offer a refund.)
Are Virginia customers being sold a version of Iron Man 2 that has apparently been censored by (or censored by the producers at the request of) the Chinese government? Absolutely bizarre.
UPDATE: @ComcastCares tweets, "We have just been made aware of this yesterday and are working on it."
