Warner Bros. Japan calls out Warner Bros. over Barbenheimer meme
Understandably, some people don't find the "Barbenheimer" meme to be a light-hearted joke

Warner Bros. Japan doesn’t find “Barbenheimer” amusing and it’s letting Warner Bros. U.S. hear about it. In a statement released on Twitter today, Warner Bros. Japan criticized the Twitter account of its own film Barbie, calling on its parent company to “take appropriate action.” On July 20, one day before the release of the two films, @BarbieTheMovie responded to “Barbenheimer poster art” tweeted by @DiscussingFilm. “It’s going to be a summer to remember,” the Barbie account replied.
Unfortunately, not everyone finds the meme so light-hearted. In Japan, where Oppenheimer has yet to receive a theatrical release, Christopher Nolan’s biopic has re-opened decades-old wounds caused by the American military’s use of two atom bombs on the cities of Hiroshima and Nagasaki. The bombs are estimated to have killed between 129,000 and 226,000 people.
“We consider it extremely regrettable that the official account of the American headquarters for the movie Barbie reacted to the social media postings of ‘Barbenheimer’ fans,” Warner Bros. Japan wrote in a statement posted to the Barbie Japan Twitter. “We take this situation very seriously. We are asking the U.S. headquarters to take appropriate action. We apologize to those who were offended by this series of inconsiderate reactions.”
