Other mistake: In the cave we see Tom Hanks drawing an analemma without a precise timekeeper, which is needed to draw one. What he could have done is a meridian rect, which is build with the meridian time. The analemma is the differential chart between the solar time and civil time.
Other mistake: When Wick is delegating climbing routes, he tells part of the team to climb "Hockey Stick Gully." This route is known as the South Face or Polish Line and although climbers can climb it, no-one has since 1986 because it is an extremely dangerous route due to the amount of technical climbing and avalanche exposure. Climbing this route in a rescue attempt would almost certainly result in more casualties.
Other mistake: Either there was or wasn't a 5-year contract from the onset. At first, Sherwood told Bob, "It's just a pilot episode. If we get picked up for a series." Narrator Barry Williams said his agent called to tell him "the network picked up the Brady Bunch for a full season." Season One ended but Sherwood didn't call "until the last minute" to tell the cast they "would be coming back to a second season." Later, Sherwood told Bob that he knew when he did the pilot that he signed a 5-year contract. (00:05:50 - 00:21:40)
Other mistake: Luther tells Ethan that he will only have 40 seconds for the louvres to remain open for him enter the ventilation shaft at Biocyte before the alarm goes off. But the warning message on Luther's computer says that the limit is 20 seconds. (01:06:30 - 01:09:10)
Other mistake: The timing was way off from the couple visiting from midnight Mississippi, to the actual kidnapping, and she said they had visited last week.
Other mistake: When Martin and his younger sons attack the soldiers Gabriel sent to their camp, the body count totals 20. That includes the private who gets up and tries to run that Martin hacks to death. Later when Tavington is questioning the wounded private the Cherokee scouts brought in, he indicates he was in the fight. But Tavington states 20 soldiers were killed and the ambush shows 20 being killed. Where did the private come from?
Other mistake: When they've duct taped the cop to the x-ray machine to check the outcome of the procedures Oz did on his teeth, there is no film in his mouth as the machine takes the x-ray. (01:17:20)
