Months after the series ended, the show’s creators David Benioff and D.B. Weiss have finally spoken out about the blunder to Japan's Star Channel.
"We're concentrating so much on Daenerys and Jon Snow … that we just didn't see this coffee cup right in the middle," Benioff said.
"So at first I couldn't believe it and then it was kind of embarrassment because how did we not see that coffee cup in the middle of the shot?”
"And then eventually, it was just kind of funny because this one is just a mistake and it's kind of funny to us now."
“It’s, like, you know, I think in Persian rugs, it’s tradition that you make a little mistake when making the rug because only God can do anything perfect,” Benioff explained. "That's why I put the coffee cup there," Weiss joked, saying the placement was a "conscious, concerted statement … of imperfection".
