That's also how there was an almost Star of David in the goblin bank in the first Harrt Potter movie. I recall getting into a reddit argument with the position it was weird no one thought to move the rug for the shot. Cause it's pretty hard to tell how the one point difference on the star and it's already a goblin bank and also movie sers have like a hundred people on during filming and hundreds more deciding how everything is going to go do and look before filming. Like, even if the looks like a star of David in a goblin bank part wasn't caught then the Australia part still breaks immersion, they couldn't spring for a fucking rug in this multi million dollar movie?
