Continuity mistake: In the scene where Silk Spectre II visits Nite Owl II at his home, the small mole on her cheek disappears only to reappear again when they leave to visit Hollis Mason (Nite Owl I). It doesn't appear to be a staple of Spectre's makeup in any way and is instead permanent, as it was present when she left Dr. Manhattan to visit Nite Owl (directly before) and on the way to visit Hollis (directly after) as well as through the rest of the film.rebeccafay
Revealing mistake: In the scene in the Vietnamese bar, after the Comedian shoots his ex-lover and she falls to the floor, the camera shows a quick, panned-out shot of Dr. Manhattan and the woman on the floor. The bottom of her shirt is flipped up, revealing straps of the false pregnancy stomach she was wearing.rebeccafay
Revealing mistake: When Dr. Manhattan is interviewed on TV, his ex-girlfriend Janey makes a surprise appearance in the television studio and launches into emotional accusations. In one shot, we see both Janey shouting in the background and a live television monitor close-up of her face in the foreground. However, the TV monitor close-up shows Janey making completely different head movements than she is making in the background.Charles Austin Miller
Continuity mistake: In "The Ultimate Cut" version of the film (and perhaps the original), Laurie and Dan have a discussion in a restaurant about the attack on Ozymandias. Outside, across the street we see people milling about. As the camera cuts between shots of both characters at the table, then close ups of Spectre, then of Night Owl, and back again, the positions of these people vary randomly, including a seated girl that appears instantly out of nowhere, then a man in a brown jacket walks over to join her, but instantly is seated next to her, then he's seen approaching and sitting down with her. (Timecode is for The Ultimate Cut). (01:41:10)johnrosa
Factual error: In the scenes on Mars, two spherical moons can be seen in the background. However, in reality, the moons of Mars (Phobos & Deimos) are not spherical. Also they are so small, that they would only appear as moving dots in the night sky, not spheres like Earth's moon.
Continuity mistake: When Kovacs is being interviewed before being given the Rorshach test, a pill bottle is shown on the table in front of him. The front label of the bottle faces Kovacs when first seen, but a moment later, with nobody touching it, the bottle has turned 90-degrees so that the label faces left of Kovacs, toward the camera. (Timecode is for The Ultimate Cut). (01:50:50)johnrosa
Continuity mistake: When Dan returns home after talking to Mason, he finds Rorschach in his kitchen eating beans from a can. After he has finished eating, he throws the second can on the table where it lands next to another can. When he gets up, the two cans have moved significantly apart. (00:20:15)ployp
