Visible crew/equipment: Behind West, when he's suspended over the electrical field, you can see the shadow of the boom mike and rigging pole moving on the wall.

Visible crew/equipment: When the Eccentrics outline their nefarious plan to assassinate Juarez, the boom mike shadow is moving on the door behind West and Gordon.

Revealing: Tony throws two knives at West - but on the wall where the knives hit, the rectangular openings from which the blades actually emerge are delineated beforehand. Happens again a few scenes later, where slots cut in the door are already there before the knives are thrown. [Spoiler: It's inconsequential to the "revealing" error, but if you play the scene in slow motion, you can see that both times, the knives pop through from the back of the "wall." This is also how the carnival trick is performed.]

Visible crew/equipment: West walks through the gate into the amusement park and twice passes very visible truck tire treadmarks in the dirt street.
