Character mistake: Since the Book of Revelation ends with Satan being defeated, Damien and his followers should be aware of this. That's why it makes no sense that they keep quoting from Revelation since it ends up spelling their demise (it does not predict that the Anti-Christ will destroy the earth as they keep claiming).
Character mistake: Chapman is wearing a gold oak leaf cluster insignia on his uniform which is the rank of Major. At the initial briefing he is introduced as Major, which is correct. Throughout the movie he is referred to as Captain, which is wrong.

Unfortunately, Sir Francis Drake Boulevard doesn't go anywhere near Santa Rosa, it heads west through Marin County and ends up near Pt. Reyes. They should have stayed on the highway and kept going north to get to Santa Rosa. (01:27:25)
Character mistake: When Travis is buying guns, Easy Andy (the gun salesman) makes a few errors. Firstly, he states that the Smith and Wesson 61 Escort is a "Colt .25 Automatic." Secondly, he calls the Astra Constable a ".380 Walther." And lastly, he talks about the ".380 Walther" saying "during World War II, they used this gun to replace the P38. Just given out to officers." This is also incorrect.

Character mistake: At the scene at the dinner table where Pat and Tiffany meet, the prescription drug "Trazadone" is mispronounced with a long A as in "trayzadone." This a fairly common drug used for depression and as a sleep aid. Any nurse or pharmacist could tell you the correct pronunciation. Interestingly, the other lesser known drugs were pronounced correctly.

Character mistake: Clark has too many lights on his house causing the city to go dark. There is a scene where the power plant needs to boost their output. There is a close-up of a guy flipping the switch. Look at the way they spelled auxiliary - auxilliary. (00:37:54)
Character mistake: The check written by Sam Jackson says May 2, 1858. At this point in the movie, it should be 1859.
Character mistake: When Will Riker comes to Troi's office and kisses her, Troi says that she has never kissed him with a beard before, but in the third season episode "Menage a Troi", Troi does in fact kiss a bearded Will Riker, while on leave at Betazed, in the Fifth season "The Outcast", and again in season six's "Man of The People."

Character mistake: In one scene, one of the people suggests that Danny Ocean should run for President, and the first plan of action was to repeal the "13th and 20th" Amendments to the constitution, allowing women to lose the vote and go back into slavery.

If the 20th Amendment were repealed, the President would again take office on March 4th in the year following the election.

When he looks at Roman's folder there are a couple of shots where they show information about him.

Character mistake: In the President's speech he says that 'The Bible calls this day Armageddon'. That is not correct.

Character mistake: The laser pointer and the subtitle reads "Gemeinschaft Bank". That's wrong. It has to be Gemeinschaftsbank. (00:04:20)
