Starbucks responded to Sunday night's Game of Thrones coffee cup gaffe. Marketing firms have estimated that the coffee company has received over $11 million in free publicity. But the catch is, the cup isn't even from Starbucks!
Hauke Richter, 'GoT' Art Director for the past 5 seasons, tells TMZ ... the notorious cup is NOT from Starbucks, but rather a local coffee shop in Banbridge, Northern Ireland near where they filmed.
Richter says despite the hoopla and theories about the cup, he's certain it was just an accident. He says similar mistakes -- like Vikings or Indians wearing wristwatches -- happen on TV and in movies all the time ... they're just not as high-profile as 'Thrones.'
He adds ... "We are usually so diligent that this does not happen. The shoot was very hard and demanding and it is likely that after a very tiring ep 3 shoot, this was simply overlooked by an exhausted crew."
