The Night of the Bubbling Death - S3-E1
Revealing mistake: As West drags the body of a bad guy out of the scene, the supposedly unconscious man is holding his head up so as not to have his head dragged through the dirt. A truly unconscious person's head would flop back on to the ground.
Man's Best Friend Is Not His Dog - S4-E6
Revealing mistake: As Schultz holds Newkirk's hat during the search, you can see "Dawson" written on the inside band. This was to insure that Richard Dawson (Newkirk) always had the right wardrobe pieces.
Revealing mistake: On 10/9/06, John entered the storage facility and reached towards the light cord. He formed a fist, as if grasping the cord, but his hand was actually several inches from it. It was clear that he was not actually holding the cord at all, but then he pulled his fist down and the lights went on.
School Days - S1-E3
Revealing mistake: When Max is being attacked with throwing knives, one is thrown into the closet door. Watch closely; the wire used to guide the knife is visible.
Meet My Master's Mother - S3-E9
Revealing mistake: The "ocean" behind Tony and his mother is a painted backdrop; the waves aren't moving. (00:20:10)
There Were Giants in the Earth - S1-E5
Revealing mistake: The Robot's lights wink out for a few seconds as it disables the force field.
Revealing mistake: During his scuffle with the intruder, Kelly's stunt double's face is visible in several shots. (00:06:40)
Urutora sakusen dai ichi gô - S1-E2
Revealing mistake: When Bemular shoots his beam at Ultraman, the special effect actually does superimpose over part of Ultraman's leg as if he were hit, which is not what happens. (00:22:05)
Revealing mistake: Oliver and Eb cast shadows on the painted backdrop as Mr. Haney drives up.
