Snow Falls - S1-E3
Visible crew/equipment: When the horse carriage is ambushed, just as Princess Abigail can be heard screaming "Please, help me", the camera pans downward and a horse wrangler wearing a blue baseball cap can be seen in the lower left hand corner, hiding behind one of the horses. (00:03:20)
Winterfell - S8-E1
Visible crew/equipment: After Sansa tells young Ned Umber to hurry back to Last Hearth and bring his people to Winterfell, when Jon tells Maester Wolkan to send ravens to the Night's Watch, in the next shot of Wolkan the chalk T-mark can be seen on the stone floor in front of his feet (it's not the stone's edges or cracks).
