Continuity mistake: 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 mistake: During the final confrontation in Veidt's lair, you see the actor Billy Crudup in his SFX suit reflected in Nite Owl's goggles, not the image of Dr. Manhattan.
Trivia: This is for the trailer rather than for the final film, but worth a look. At 1:33 in the trailer, just after seeing Rorschach slam someone against a wall, we see another fight. Pause it and look at the guy in black - he's holding a walkie-talkie, which in the next shot becomes a gun. This is only trivia, not a mistake, because it's only valid for the trailer. The MPAA don't allow guns to be pointed at the screen in trailers, so Zack Snyder, in a tribute to the infamous gun-editing from E.T., replaced the gun in that one shot with a walkie-talkie.

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)

Answer: Moloch knowingly worked for Adrian at one time, installing carcinogenic gas canisters in ventilation ducts to give people cancer at the high-energy research facility. That's how Moloch developed terminal cancer; but Adrian killed Moloch with a bullet between the eyes before Moloch could reveal any more information to Rorschach. Adrian then set-up Rorschach for murdering Moloch. Anyone who worked "on the inside" of Adrian's plans or who might be an obstacle to those plans was a target for assassination. Adrian murdered his super-associates (The Comedian and Moloch, and he later attempted to kill Dr. Manhattan), he murdered his own hit-man, and he murdered his entire staff of scientists in order to protect his secret plans.
