The Conjuring 2 (2016)
Revealing mistake: When the girl is hanging from the ceiling her hair is following what gravity normally does. This gives away that the set is actually upside down and she is really on the floor. If she were stuck to the ceiling her hair would've been down on her face.

Friends (1994)
The One With Rachel's Going Away Party - S10-E16
Revealing mistake: The twins are dolls. They don't move, and the way they are being carried indicates they don't weigh much.

The X-Files (1993)
Revealing mistake: The answering machine at The End appears to not be plugged into any phone line. The shot shows the phone jacks on the right side of the machine are empty. In order for an answering machine to work at least one of those ports would need to be hooked to the phone.

McLintock! (1963)
Revealing mistake: Most if not all of the punches thrown by everybody involved during the fight at the clay slide do not land. There are even two men fighting in the pond that appear to be slapping each other, but it looks incredibly fake.

Quantum Leap (1989)
A Tale of Two Sweeties - February 25, 1958 - S5-E12

The Santa Clause (1994)
Revealing mistake: When the elves are tying up the police officer at the station, they do so in a really quick manner. The film here is obviously sped up. You can tell this by the fact that the children playing the elves are breathing really fast.

It's a Wonderful Life (1946)
Revealing mistake: When George comes home flustered, his kids are hanging on him. Right after Mary closes the door keeping the littlest boy out, she walks into the kitchen. Watch this scene carefully as the camera tracks backwards. A bad jump cut is obvious.

Quantum Leap (1989)
Leaping of the Shrew - September 27, 1956 - S5-E3
Revealing mistake: The background while Scott is on the raft with Brooke Shields is blatantly a studio wall. The clouds have streaks on them with dark colors and the seam where the ocean meets the wall can be spotted. The film "The Truman Show" used the same technique.

The Karate Kid Part II (1986)
Revealing mistake: When Daniel and Kumiko first see the storm coming near the end of the film, the wind outside is blowing the trees sideways. They open the door to run out and the camera shows what is outside. The trees there are not moving.

Little House on the Prairie (1974)
Revealing mistake: During the scenes when they are chasing the balloon in the prairie, the tire tracks from the camera car are easily visible.
Upvote valid corrections to help move entries into the corrections section.
Suggested correction: I just watched the episode and the tire tracks look to be the same shape as the tires from the wagons that are moving people around (such as the firefighters). It didn't look really thick like automobile tracks, so those seem proper to appear.

Die Hard 2 (1990)
Revealing mistake: McClane jumps out of the helicopter at the end and lands on the wing of the larger airplane. The stunt man who does this then proceeds to move up to a long wire on the side of the wing. Any normal airplane would not have a long wire on the wing.

Quantum Leap (1989)
A Song for the Soul - April 7, 1963 - S4-E15
Revealing mistake: When Al jumps into the shot out of nowhere on the steps after the record producer leaves, Sam and the two girls abruptly move, giving away the technique to achieve Al showing up. The transition is usually smoother, this one happens to be rough and noticeable.

The Walking Dead (2010)
Revealing mistake: After it starts raining there is a shot looking at the road in The Distance. Notice how the rain is only falling in a small area and stops just beyond where the group is at. The road is dry from there on out.
