Let's start with the classic example — when Game of Thrones left this coffee cup in a shot:
Let's take a closer look:
When Ron's stunt double was very visible in the chess scene in Harry Potter and the Sorcerer's Stone:
This was Ron a second earlier:
And then here's "Ron" just before he sacrifices himself:
When McGonagall's chalkboard was backwards in Harry Potter and the Chamber of Secrets:
This one's especially weird to me, because it looks like the other chalkboard is the right way in the wide shot, so it's not like editors just mirrored the image. The above chalkboard is actually backwards:
When a cameraman was visible in this Moon Knight scene:
And when a crew member's legs were visible in this scene during the next episode:
The moment is at Episode 4, 18:23 and can still be seen on Disney+.
When a crew member was similarly visible in a scene in The Mandalorian:
This moment also seems to have been removed on Disney+. It was around 18:53 during "Chapter 12: The Siege."
Let's take a closer look:
When Freaky Friday used a MUCH older stunt double for a kid and this TikTok caught it:
Let's take a closer look, because this is *definitely* not a little kid. This person has wrinkles:
When Friends used a Rachel stand-in that wasn't even wearing the same shirt:
Here's the shirt Rachel was wearing just a second prior:
And here's the stand-in again (her hair is also darker):
And when they used a stand-in for Monica:
These errors occurred largely because Friends was converted to widescreen, which it was originally not meant to be viewed on.
When a crew member in a baseball hat could be seen walking in the back of this Braveheart shot:
Here's a closer (but very blurry) look:
I kinda think they do it at home after watching the movie or show as a hobby.
Well, I think that in most cases you just notice it.
