Continuity mistake: When the Faith Militant descend on Ser Loras Tyrell's training session there is a shot after the Militants have come down the stair of Loras fighting from behind a man's shoulder, in this shot you can see they are fighting on grass surrounded by walls with sheer drops with no entry point other than the stairs the militants walk down. In the next shot you can see the 9 militants that have come down the stairs approach Loras from one side, but suddenly 6 militants join him from the opposite side, where they definitely were not before. In the zoomed out shot you can see there is nowhere for these men to have come from. (00:11:15 - 00:11:50)
Continuity mistake: Towards the end there is a body of a dead Son of the Harpy lying between the fallen Unsullied and the side corridor visible in the wall, located very close to either. In the next show the body is gone. Also, as the camera angle changes, the blood stains on the walls look differently. (00:48:50)
Unbowed, Unbent, Unbroken - S5-E6
Continuity mistake: When the Sand Snakes attempt to kidnap Myrcella, as Nymeria Sand runs up to Myrcella to seize her, she is holding her large whip in her right hand. However, in the very next shot, the whip has disappeared, and Nymeria is now holding a dagger in her hand instead.
Continuity mistake: In the scene in the amphitheatre, while seated in the royal box, Daenerys is wearing a full length white gown with flat pumps and an ornate silver necklace with a large dragon motif on the left side. During the revolt when she is seen running across the fighting pit the dress is shorter and she seems to be wearing some sort of leggings underneath it. Daenerys escapes on the back of her dragon and when we next see her in episode 10 she is wearing a completely different knee length pale blue gown. The necklace also seems different with her hair spread out on her left shoulder to disguise the lack of the dragon motif. She is also wearing grey boots with a fairly high heel. Obviously dragons come with a secret baggage compartment.
Continuity mistake: While Jaime and the High Sparrow are standing beside Myrcella's body in the Sept, in the overhead shot of Myrcella her right hand is placed over her left hand, but in other shots it's the opposite way. (00:18:30)
Continuity mistake: In one shot Sansa is writing a letter to Petyr Baelish, and is pressing a seal onto hot wax on the lower right corner. The next shot Sansa raises the letter, and the wax is gone. (00:39:45)
Battle of the Bastards - S6-E9
Continuity mistake: When Jon Snow is all alone in the field drawing his sword to fight the incoming enemy cavalry, behind him we see an empty field. but seconds later as the enemy cavalry is near him they are met by Jon's own cavalry from behind. (00:37:30 - 00:38:20)
Continuity mistake: When Sam hands the bureaucrat the letter from Jon Snow, in the shots facing the bureaucrat, the wax seal is on the left side of the envelope (when seen from Sam's perspective). In the shots facing Sam, the seal is on the right side of the envelope.
Continuity mistake: When Drogon comes flying over the hill, he overtakes the front of the Dothraki line in the shot where he roars, but in the next shot, he's behind the line again.
Continuity mistake: In order to save him from Drogon's fire at the very end of the episode Jaime is thrust by Bronn into water about 40 feet deep. This shouldn't have been possible especially after Jamie is shown galloping on his horse along the watery beach side just moments before.
Suggested correction: As shown in the following episode, the undercurrents had carried them some distance down-river.
An undercurrent may explain how they eventually got to the other side of the lake but not why the water on the shore became so deep so quickly.
A Knight of the Seven Kingdoms - S8-E2
Continuity mistake: During the battle strategy meeting around the table, Sansa wears the long silver chain and circle neckwear, and the long chain changes the way it is placed through the circle. Sansa's chain is put through the circle in a way that's over and under in most shots, but when Jon explains that if the dragons are in the field they won't be able to protect Bran, the long chain is put through the circle the opposite way, under and over. (00:30:05)
A Knight of the Seven Kingdoms - S8-E2
Continuity mistake: When Gendry gives Arya the dragonglass weapon that he made for her, in the following shots Gendry's leather cloak straps switch between being crossed with his left strap over the right strap, or his right strap over the left strap. (00:43:00)
Continuity mistake: When Arya stabs the Night King it's high on his chest, piercing his leather armor. In the next wide shot, the dagger is lower and not in the armor.
The Last Of The Starks - S8-E4
Continuity mistake: When Sansa puts the Stark pendant on dead Theon she only puts it through one leather strap, then when it cuts it's through two straps. (00:05:15)
The Last Of The Starks - S8-E4
Continuity mistake: In this episode, Kings Landing is shown as sitting on flat, plain-like terrain. In previous seasons, it was shown surrounded by water and mountains covered lush greenery.
Suggested correction: That is correct, however there is actually a reason for this, it was just never adapted from the books. Stains burned the woods during battle of the black water as an offering to the lord of light.
That doesn't remove the hills though.
Continuity mistake: When Grey Worm leads Tyrion to the Dragonpit, as they pass the column of Unsullied their long individual shadows are directly to their sides, but in the next shot the Unsullied are seen in the background and the shadows are entirely different. (00:46:00)
Continuity mistake: During the meeting at the Dragonpit, Sansa is wearing her long silver chain and circle neckwear, with the long chain changing the way it is placed through the circle. First the chain is put through the circle in a way that's over and under, but in some shots the chain is put through the circle the opposite way, under and over. (00:53:10)
Continuity mistake: When the episode starts Arya is walking towards where Daenerys is and has her face covered in mud and soot, plus a long streak of dark dry blood running through the right side of her face. The next time we see her her face is cleaner and the blood is less noticeable. In further shots the amount of blood increases or decreases randomly. There doesn't seem to be much water and soap around the place.
Continuity mistake: When Daenerys is dead she has blood underneath her back and hair, and as the camera is above her, her right arm is curved or bent a little. When Drogon picks her up her arm is now straight and despite the blood on the ground she seems to be completely clean. No blood on her back, hair or scarf. Then as Drogon flies away, how on earth did he pick her up with his left hind leg? Did he twist his leg 180° to pick her up with his front claw?
Continuity mistake: When Daenerys dies, in the close up her head is parallel to the ground, looking up at Jon. Cut to a wide shot and her head's hanging much further backwards, plus her eyes are suddenly closed.
