Revealing mistake: At the end it is not Helen against the filing cabinet - the face is different. Obviously a body double.
The Illusion of the Lethal Playthings - S1-E20
Revealing mistake: The "remote control" model plane lands and sneaks through some bushes to spy on Blake. You can see the filament line pulling it. And the picture it sends the bad guys with its mini-camera not only zooms in (unlikely technology in 1973), it also delivers an unobstructed view when the plane is sitting in foliage that should block part of the shot. (00:21:50)

Revealing mistake: Oliver Babish's office has windows in a location it can not possibly have them. Jed and Leo are in continuous conversation as they leave the 'normal' West Wing set at the end of a hall (See http://www.whitehousemuseum.org/special/wwtv.htm where the words 'Press Briefing Room' are - that's where they turn to their right). They walk a few steps then turn right again and ahead of them is Babish's office, with windows straight ahead. If this had been a single continuous set, Babish's office would be located in the stair area to the left of the press briefing room, and the windows would offer a view of the hallway that runs between the lower corners of Leo and C.J.'s offices (seen at 3:36), not the outside world. (00:03:30)
Revealing mistake: When Allison is "seeing" the Massey house going up in flames, James flinches when the painting falls off the wall behind him, even though it is only supposed to be happening in Allison's vision.
Revealing mistake: As Dr. McNamara is marking Megan O'Hara for her breast reconstruction surgery you can see the lower line of her prosthetic "removed breast" from her mastectomy on her left side. It is not the surgical scar from removing the breast, that is visible about an two inches higher closer to where the nipple should be. My aunt had a mastectomy, I know there should be no scar here.

Mother and Child in the Bay - S2-E2
Revealing mistake: When Bones and Booth are driving in his SUV talking about Abraham in the Bible, you can see that Bones' side window is lowered almost all the way down, but her hair is perfectly still and not being blown around as it normally would be.
