Werner said this during an interview with Piers Morgan a few weeks ago (via The Hollywood Report):
During a recent appearance on the show Piers Morgan: Uncensored, the host asked Herzog if he was Team Barbie or Team Oppenheimer — the two films that led the “Barbenheimer” phenomenon last summer.
“I have not seen Oppenheimer yet, but I will do it,” the director admitted. “Barbie, I managed to see the first half hour, and I was curious. I wanted to watch it because I was curious. And I still don’t have an answer, but I have a suspicion. Could it be that the world of Barbie is sheer hell?”
It could be, Werner. It could be.
