Other mistake: When Fry is looking around for Riddick at the end, she's holding the blue bottle of bugs to light her way. The blue light on her face isn't from the bottle as she holds it, as she's circling around in some cases with the bottle completely behind her, yet her face is still lit up blue.
Other mistake: When Caleb and Luke are stealing the snake weather vane, when they fall into the moat, you can see the snake floating. This weather vane is presumably made out of metal and should sink like a rock but you can see it floating when they fall.
Other mistake: When Proximo says "Use this" to Maximus and throws him a piece of body armor, it is not the same armor he uses in the scenes that follow. (01:10:00 - 01:12:55)
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: 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)
