Chuck Versus the Gravitron - S2-E8
Revealing mistake: In the scene where Ellie is testing her Thanksgiving turkey by giving Morgan a piece, when she throws it in the trash he says 'no no no Sarah.. what are you doing!', which is the actor's name (Sarah Lancaster), not her character's. Maybe edited in some versions. (00:09:40)
Revealing mistake: After Sam shoots Spencer with her blowgun, she lands on the ground after jumping from the ceiling. During this shot, you can easily see that it is a stunt double.

Revealing mistake: When Clara is filming her kids, we see her daughter operate the car. When she's supposed to have put the car in gear and have driven forward, you can see the scenery move in the background, showing that the car was stationary and the camera was just violently moved to the right to simulate the act of the car moving.
Fantastic 4 Rise of Silver Surfer - S11-E37
Revealing mistake: When Rob grabs Critic and Malcolm and shoves their heads out the door to see that the world is on fire, both before and after it shows the clip of a city burning you can see in Malcolm's sunglasses the reflection of the perfectly fine and normal suburban street. But they should be looking at a burning city. (00:01:30)
