Factual error: When Martine enters the passcode to reveal the bats, you see her hit "3" first followed by what seems to be "5" (the rest is blocked by her body). She then tells Michael his passcode is the first 6 digits of pi backwards. The first 6 digits backwards would be "951413."
Factual error: Pettis' calculation of the amount Connor needed to replace his asset was way off. He stated, "[Cornell] brought me about 250 [$250,000] a year. He had at least 20 more years of service. Subtract five years he might have spent in prison, so you owe me, what? Six point two million." Pettis was presented as intelligent, but a quick mental calculation of even the full 20 years at $250,000 would total only $5 million (not $6.2 - an odd sum). For 15 years, the total would be $3,750,000. (00:28:45)
Factual error: The movie is set in the Northern Great Plains of the United States, and the tribe is identified as Comanche, but the Comanche were located in the Southern Great Plains, across present-day northwestern Texas, eastern New Mexico, southeastern Colorado, southwestern Kansas, and western Oklahoma.
Factual error: Sam Cooper's Rx label was for Alprazolam (generic Xanax) 2 mg, qty #150, refill 2x, and "take 1 tablet by mouth as needed." "Must last _" length was not visible and there could have been warning stickers (may cause drowsiness) on the other side. However, Xanax is a fast-acting tranquilizer which should last 6 hours and the dosage should not exceed 10 mg per day. The instructions to "take 1 tablet by mouth as needed" should have had restrictions attached to prevent serious side-effects/death. (00:49:38)
Factual error: The film gets basic physics wrong while trying to depict relativity. Buzz Lightyear leaves T'Kani Prime for a trip around its sun, travels with near-light speed, and returns four years later. This could only have happened if T'Kani Prime's sun were at least two lightyears away! It gets more ridiculous. Buzz's last trip takes 26 years, even though he has traveled at faster-than-light speed. Overall, T'Kani Prime is experiencing either a mysterious time slow-down or a rapid orbit expansion.
Factual error: When the Allosaurus bent over to pick up her egg (which was almost touching a newly-thrown hand grenade), the hand grenade exploded only toward the right of the screen, engulfing the dinosaur. A hand grenade would/should explode in all directions. (01:19:30)
