Other mistake: The Protestant church where the boy's funeral is held has a huge painting of the assumption of Mary to heaven. This is a Roman Catholic doctrine and no Protestant church would have such an image. Even if the congregation bought their building second hand, surely the painting would have been covered up or removed.
Other mistake: When Aaron is asked how he pleads, Vail instructs him to not answer and invoke his Fifth Amendment right. He then presents the judge with case law that supports that instruction. Roy attacks Martin after the doctor has left the room. That means the evaluation is still being completed. But after the attack, Vail tells the doctor he cannot change the plea in the middle of a trial. There could not yet have been a plea because the evaluation was still being done.
Other mistake: When the dentist is doing Jody's teeth, any time they are showing the reflection of his teeth through the tooth mirror, you can tell those are not the teeth of a little boy but those of an adult.
Other mistake: The power is cut to the satellite facility near the end, but Sheen manages to raise a powered window curtain to look outside.
Other mistake: During the ending US Supreme Court scene right before Alan Isaacman proceeds with his opening statement, Larry Flynt can be seen standing up instead of in a wheelchair. (01:55:53)
Other mistake: After they cross the water their clothes appear dry.
Other mistake: When we see the front page picture of Mike with the alcohol and joint, he's pouring the alcohol over his bottom lip and chin, going down the front of his shirt. This doesn't match what we see him do. It does appear that Mike spilt alcohol on himself when off camera, but the wet spot is on the right side of his jacket, but not down the front.
Other mistake: During the "Hellfire" sequence, when Frollo is singing "God have mercy on her, God have mercy on me...", his shadow against the wall behind him rises as he backs up closer to the wall. However, when he turns around to press against the wall, his shadow ends up far above his body when it should have become level with his body by that point - like the very next close-up shot of Frollo shows, which is itself a continuity error.
Other mistake: This mistake is actually about the DVD box art. On the cover, George Clooney is pointing his revolver outwards. A revolver has rear and front sights, but if you look at the front of the barrel of the revolver you will see the rear sights and front sights both there. The rear sights are supposed to be on the backside of the revolver, but on the cover the rear sights are actually in front of the front sights. No revolver works like that.
Other mistake: It's said to be winter there, what looks like snow is shown in the sister's yard yet for two days Alex goes out in a mini skirt.
