Continuity mistake: The Zeon mobile suits land on the exterior of the colony and two of them operate the locks that allow them to enter. In close-ups, they both cast a shadow behind their back (so, in opposite directions, since they are to the right and to the left of the hatch), but in the establishing shot they both cast a shadow in the same direction. Also, the floor itself does not have the same markings between shots. (00:03:20)
Continuity mistake: Amuro stopped the car in front of the location where the two Federation officers die in the explosion, at a certain distance. When he is shown reading the manual with everyone running away from the shelter, the damaged car got closer and it is almost inside the hangar. (00:11:00 - 00:13:00)
Continuity mistake: Seeing the rocket fired by the Zeon, Amuro gets on the ground. In his reaction shot to the horror of the hangar with two men entirely scorched by the explosion, he has debris on his arms, that were clean in the shot before. (00:11:30)
Continuity mistake: The cover of the Gundam instruction manual on the ground changes from just blank white with a little horizontal line, to the logo with two of those lines and without the superscribed dot, to the full logo. It also rests on a ground differently littered with debris from the explosion. (00:11:50)
Continuity mistake: When Fraw Bow gets up and away from Amuro's arms to run to check on her mother, the Gundam manual disappears momentarily from the scene. (00:15:15)
Continuity mistake: Fraw Bow cries on her mother's corpse that is on the ground face down. Amuro walks to her to console her (and to bitch slap her) and the woman is lying face up all of a sudden. (00:15:25)
Continuity mistake: Amuro climbs on the Gundam that is lying down and gets where the tarp covering the cockpit is. The manual is face down in the first shot, but is face up and rotated differently in the next shot, when he unveils it. (00:16:30)
Continuity mistake: The distance between Char and Sayla when she holds him at gunpoint diminishes greatly between shots - to the point that he can just kick the gun off her hand. (00:13:00)
Continuity mistake: When Char boldly dashes into White Base with his jetpack, Sayla is sticking out of the Gundam hand positioned differently between shots. (00:14:00)
Plot hole: Char is able to escape from Side 7 simply flipping a couple grenades he had on his person (shaped like the old style pineapple grenades) who tear huge holes into metal walls with a visible thickness in excess of a meter, including the outer wall of the space colony a salvo of Mega Particle Cannon from the battleship didn't break. If Zeon has such explosives at their disposal, then maybe they should not fight with battleships and giant robots, but simply have footsoldiers toss tiny grenades at the enemy. (00:15:00)
Continuity mistake: When Amuro returns from his mission and enters the bridge of White Base, Sayla at her station has a man with a broken arm next to her. When she was seen earlier manning the engineer station, the officer next to her had just a bandaged head; the one with the broken arm was the one instructing Hayato about the missile controls. (00:16:50 - 00:21:45)
Other mistake: Bright gets notified that one of the two Zakus is approaching at a velocity 3 times higher than a normal mobile suit's. However, the two dots on the radar (Char and his subordinate Slender's) move in parallel at the same speed. (00:18:15)
Continuity mistake: Char is talking with his superior about the lackluster reinforcements. In the first shot the console gauges behind his commander are lit of a bright yellow; when we get a closer view of the man, the console has a duller light and the part on the right is arranged differently. (00:04:15)
Other mistake: Amuro's strategy relies on attacking the enemy having the sun behind himself, but when Ryu sees the Musai for the first time it is clear that the sun is behind Char's ship. (00:10:20)
Other mistake: During the loading operation of the Zakus, the catapult is broken, and one of Gadem's subordinates dies in his arms. The guy has been hit by a salvo of bullets from the Core Fighter, thick enough to make holes in the ship hull, but no hole whatsoever in his spacesuit, visible entirely. (00:17:15)
Continuity mistake: At the end of the episode, Amuro takes his drink from Fraw Bow's cart holding it with his left hand - his right is occupied by the helmet. However in the next shot here he is, holding it in his right hand. (00:22:45)
Continuity mistake: The cart with the prison meals is carrying 5 trays the first time it is shown in close-up. Inside the cell though, Kai takes his from a pile of 6. (00:08:40)
Continuity mistake: Amuro is explaining to his cellmates the key of the Gundam's combat abilities. He is sitting on the floor with Kai, but as the angle changes, the back of the sofa in the background is at an height that would make sense only if they were sitting on a chair. (00:10:40)
Other mistake: Bright realises that the door is unlocked as he pounds on it. The sliding door opens just a little, and the power is off, so it is implied and shown initially that they can be moved by hand. However when they go out of the room and when they go free Sayla and the others, it looks like the door are opening by themselves, not slid open by hand. (00:12:30)
Continuity mistake: When Bright turns towards Captain Paolo Cassius to tell him about the success of their operation, his three-way front tuft of hair is curled one way, the opposite way in the close-up. (00:21:20)
