Revealing mistake: The semi-automatic handgun the gunman is shooting has no rearward slide movement after each shot is fired for the shell casings to eject. The gun is firing but it's not reloading, however it's firing several shots. This is just not possible. In a few other previous gun scenes like the Mikey Palmice hit Christopher is dramatizing the recoil by moving the handgun up and down and snapping it in a way that just doesn't make any sense.

Revealing mistake: After Tony's unsuccessful meeting with Johnny due to Christopher's inability to keep his mouth shut, while Tony and Chris are driving past stores, we can see the reflections of the filming equipment attached to the roof of their vehicle.
Revealing mistake: When Bobby feels provoked by Tony and gives him the first punch making him fall from the chair, Tony is then shown getting up. If you look very carefully, that shot actually shows Tony falling instead, so they reversed it to make it look like he was going to get up. (00:27:24)
Revealing mistake: When Tony and Bobby are fighting at the cabin, Tony pushes Bobby against the glass door, which has a pre-break section visible right before Bobby crashes into it. (00:27:27)
Revealing mistake: The Ukranian woman's body by the stairs keeps changing positions all the time (depending on the angle), despite her being dead.
