Welcome to the Family Part 2 - S2-E25
Revealing mistake: When the family releases Chloe's bubble ability for the last time in the episode the bubble machine is visible.
Suggested correction: There is no bubble machine visible.
Suggested correction: There's no bubble machine anywhere. All the bubbles are CG.
The Bridge - S1-E10
Revealing mistake: Agent Coulson turns the steering wheel several times despite the car being on a straight street.
Revealing mistake: During the attack on the Range Rover in Shanghai, China, none of the passers-by react to the gunfire in any way. An automatic weapon's unloaded into the windshield, then a window smashed with a pistol fired through it, but people on both sides of the street don't even look up, they just keep on shopping. The attack was clearly composited into generic footage of a city street. (00:00:50)
The Vision - S4-E12
Revealing mistake: Two oarsmen (or rowers) in Ragnar's boat, the first in front of us and the second from the back, pretend to have an oar but have none. (00:38:35)
Surf'N Turf/Hardcase Returns - S1-E8
Revealing mistake: In "Hardcase Returns" Skidmark uses a digital phone to track a GPS device installed on Turbo's parade car. When the keypad on it is shown, 3 letters are missing. They could have been on the keys that had nothing written on them, but we will never know for sure because nothing is on them.
Slouching Towards Bethlehem - S2-E8
Revealing mistake: When Kenya is being held at gunpoint the pistol pointed at her has a visible seam running up the grip and the back of the slide. It's a plastic prop.
Revealing mistake: After Krystal goes to the bathroom, Sarah's phone is not in call mode.
