Continuity mistake: Ide can't sleep due to the thunderous snoring in the room. He grabs the blanket; the position of the blanket under his arms changes as the shot changes. (00:03:10)
Continuity mistake: Ide jumps out of bed and quickly puts his boots on, but the boots are in a different position on the floor than before. (00:03:15)
Continuity mistake: When Arashi steps away from his slippers, those are positioned on the floor in a different way at the cut. (00:05:10)
Continuity mistake: Arashi pulls over in the street where the research station is. The car stops a few meters after the turn, but when it's shown again, it's much further into the street. (00:06:15 - 00:06:50)
Continuity mistake: The shadows on Arashi's chest when the alarm buzzes change at the cut. (00:07:05)
Revealing mistake: During his first confrontation with the alien, Hayata's pistol shoots powerful rays that don't cause a single speck of damage to the walls when the monster dodges them. They are just superimposed. (00:09:40)
Continuity mistake: At the security council meeting, Muramatsu's red pencil is along the notes' side in the wide shot, on the page itself in the closer angle. (00:10:20)
Continuity mistake: When Hayata confronts the monster that just grew to kaiju-like size, he strikes an entirely different pose (right arm forward pointing the gun, right arm back, forward and gun again) in the different shots. (00:19:30)
Revealing mistake: When the monster uses its claw to swat Hayata away, under the superimposed claw you can see the abrupt disappearance of Hayata's shadow from one frame to the next. (00:19:30)
Continuity mistake: Hayata blindly reaches for the Beta capsule that allows him to become Ultraman. He accidentally knocks it off the building. It happens twice in two separate shots and it happens differently, with either end falling first. (00:20:15)
Revealing mistake: When the monster is revealed behind a column as the troops enter the building and it splits in two mirror images, they did not stop the clock in the background, which reveals whenever they stopped filming to change things in frame.
Other mistake: At the beginning of the episode it is said that the events take place 38 hours apart. It's 2:25 PM. We see then Arashi get up in the middle of the night, so it could easily be midnight...but then he reaches the station and it's daylight, and the kid is in his car, even. Moreover, when the troops enter, a clock inside the building points 2:10.
Revealing mistake: The victims of the stasis ray in the episode try to hold still as much as possible...with varying° of success.
