Revealing mistake: Near the end, when Morgan Spurlock says "Why not do away with your Super Size options?" the water condensation runs UP the drink. (01:34:00)
Revealing mistake: When De Silva's men start to celebrate after they start building the ramp and the Zealots throw boulders down at them from Masada, the boulders bounce after hitting the ground. Big boulders like those should definitely break, not bounce.
Revealing mistake: In the scene where the geoligist's husband calls her from the L.A. airport to say he's going to try to make it home, a strong aftershock collapses the wall that the pay phone is mounted on - as this occurs you can see cables attached to the wall pulling it over.
Revealing mistake: The same scene is used as two separate shots when Pacino hits the lawyer's windshield with his briefcase. One view from the inside the car then from the outside.
Revealing mistake: After the coach [Michael Jai White] told Billy that the group of people present all chipped in to pay his entry fee, there was loud cheering ("Yeah!) but it wasn't obvious from where the cheering was coming - except when there was a close-up of a particular person. Otherwise, the people in the crowd - especially those closest to him - did not appear to be cheering. The cheering, as well as the people in the background (green screen), must have been added.

Revealing mistake: In the scene at the 1988 Monaco Grand Prix, the shot on board Senna's car is taken from qualifying, not the race. This can be shown in the shot after Senna hits the wall, as no on board camera is visible.
Revealing mistake: When the historic "Mahna Mahna" sequence in the sauna ends, the girls come out of the building running through falling snow in all their youthful bounciness. The "snow" comes from the left, at a rather extreme angle; if it were real snow there would be an awful icy wind blowing, but the girls' hair is mostly unperturbed, and in the shots that follow there's no snow at all. It's obvious that this snow is just coming from a fan kept off frame. (00:51:15)
