Watchmen (2009) - 15 mistakes

Continuity: During the prison fight scene, Silk Spectre's stiletto boot heels are alternatively flat-soled from shot to shot, for the stunt woman's benefit.

Revealing: 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.

Revealing: During the final confrontation in Viedt's lair, you see the actor Billy Crudup in his SFX suit reflected in Owlman's goggles, not the image of Dr. Manhattan.

Continuity: 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.

Audio problem: During the battle in Adrian Veidt's lair he catches a bullet. He pulls the slug from his palm but as he drops the slug we hear the sound of a spent shell casing hitting the floor (empty brass) not the heavy lead bullet.

Character mistake: While he is describing his origin, Dr. Manhattan mentions a circulatory system appearing at a military base. However, what is actually shown is a nervous system, as it depicts a brain and spinal cord.

Continuity: 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.

Continuity: 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).

Continuity: 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).

Continuity: In the flashback to the Watchmen's initial meeting, the Comedian lifts his cigar to his mouth, but in the next shot, both arms are down by his sides.

Deliberate "mistake": Though the film takes place over the course of several weeks, at night there is always a full moon.

Revealing: In the scene in which Dr. Manhattan is dressing himself, as he turns his head at the end, his CGI neck can be seen going through the collar of his shirt.

Continuity: When Rorschach throws the basket of grease on the convict in prison, the convict covers his face with his hands in pain. In the following shot, his hands are father from his face than they were before.

Revealing: When Dr. Mahattan and Silk Spectre are on Mars and they are climbing upward in his gyrating clockwork structure, a shot from well above, behind and to the right of them contains some terrible CGI work of Silk Spectre walking in a completely unnatural, very mechanical way.

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.
