Character mistake: It's all very heroic and manly but the effort put into dragging the Phoenix into its takeoff position once the engine is started is totally wasted. Townes and A.J. are both experienced pilots and Elliott is supposedly a genius aeronautical engineer - they must surely be aware that the engine power required to taxi an aircraft is trivial compared to that required to lift it into the air. Even taking into account the drag of the skids and wheels, if that engine cannot propel the aircraft at a few kilometers an hour on the ground it cannot propel it to take off speed, nor keep it up once airborne. They are not there to steer the aircraft - they are taking the strain of the whole weight of the air-frame, dragging it into place, and the energy input of eight exhausted, underfed people would add nothing to the contribution of a 2500 bhp aircraft engine in moving the Phoenix. They are not trying conserve fuel - they had enough fuel for an extended flight with both engines at full throttle, so they have easily enough to run one engine throttled back to reduce stress on the air-frame, which they say they are going to do.
Character mistake: When Buquet hangs over the scene, you can see Meg screaming along with three other dancers. Four shots later, Meg is still screaming, but the two girls who were to her right (on the left of the screen) are still dancing, as if they haven't seen Buquet yet. (01:05:10)

Character mistake: In the scene where Detective Fanning and the other cops are investigating the first murder, one cop tosses a shell casing in a baggie out the window to Fanning.

Character mistake: The most Michelin stars a restaurant can get is 3, not the 4 Adam Sandler is talking about.
Character mistake: When the mathletes advertise their poster on the desk it reads 3.14... then they make up numbers instead of following the actual number of pi. (00:01:00 - 00:03:00)
Character mistake: While watching a documentary about the Soviet team Herb Brooks says that the Soviets had had 42 games in the last three months with 42 wins. This was supposed to be said in 1979.

Character mistake: Flynn has been reading for a while, taking notes, spreading books around, etc. - when Nicole arrives and says that it was nice to watch take-off from the cockpit. The plane must have been in the air for a long time by then.
