Other mistake: Despite being a deadly marksman (only a few minutes earlier in the movie he stopped a bullet directed at him shooting it off the air), Bloodsport snipes several times at the huge kaiju featuring a massive eye in the central part of its body, and never once hits it. (01:51:45)
Other mistake: The chances that no-one in the approaching truck - three men, including a man standing in the bed facing oncoming traffic - would notice that Danny had a front seat passenger are very low, if not zero. Even after Motley got into the second row seat of the truck, but did not get down right away, the men in the truck had turned around and were following Danny but still did not notice Motley. (00:10:00 - 00:10:27)
Other mistake: Tom told David and Lily, "Whoever murdered that girl [Jessica] didn't have sex with her. They used a corn cob." The crime scene photo of the "corn cob" actually showed a partially opened "husk of corn" or "ear of corn." The "cob" is the inner part of the ear beneath the kernels of corn and could more realistically be used to "assault" someone. (00:33:30 - 00:38:30)
Other mistake: James supposedly did not give his name when he filed a complaint against Dr. Clark, which would make conducting an investigation to determine if the complaint was valid very difficult. Dr. Clark would be entitled to due process (presumption of innocence) and it is highly unlikely that the Medical Commission would have taken such quick and drastic measures against Dr. Clark under the circumstances.
Other mistake: How did Trent (who started as a six-year-old) end up with an adult-size watch and bracelet?
Other mistake: The bottle of alcohol (whiskey?) and glass on Morgan's bookcase appear to be the same as the ones the Game Master has in his office; the bottle is emptied to the same level (too similar to be a coincidence). (00:03:23 - 00:06:57)
Other mistake: When the men lift the body bag out of the boat, the body bag looks dry and there is no water dripping. (01:06:47)
