Other: Early in the movie when Shale is screening the commercial for his "services," the rolling text describing his abilities lists "Helicopter Repelling" instead of "Helicopter Rapelling".

Continuity: When Shale gets in the fight in the library, he takes a round to the upper left chest. When he takes the shirt off to reveal the vest there's no bullet and no damage to the vest.

Visible crew/equipment: At the shooting range you can see a reflection of the filming camera in the mirrors as it moves in front of the building.

Revealing: Look at the gun fired behind Shale at the firing range. The person doesn't pull the trigger, there is no flash, the slide doesn't move, there is no smoke. But the gun still kicks.
