Continuity mistake: When Prince Aegon tells King Viserys that everyone knows that his grandsons are bastards, he's looking straight at him but in the next shot he isn't.
Continuity mistake: When Park Eun-hee is talking into a video camera there are some on-screen icons for the camera: zoom, battery level, etc. Initially there are two guide lines on the zoom level bar. When the view changes then switches back a few seconds later, there is only one guide line.
