Adaptation Correction

Any author, no matter how famous, can make a mistake, and many are the cases of works that contain mistakes of one kind or another. And adaptations can change a work in a way which enrages purists. But sometimes, if the work gets a chance to be adapted to another medium, the adapters might notice, and the adaptation can be used to fix the mistake, at least in the adapted version.

A fix that causes another problem can lead to a Voodoo Shark.

Anime/Manga

 * In Jojo's Bizarre Adventure part 3, the original manga had a menu that included the Chinese characters for "fried duck" with the reading for "fried frog". This was fixed when this was adapted into episode 4 of the second season of the TV series.

Film

 * In the book of Goldfinger, there is a plot to physically steal the gold of Fort Knox (which the movie Bond points out is impossible) which includes poisoning the soldiers through the water system before they can react to such a slow method and using a nuclear bomb to open a door with everyone suicidally close. The movie changes the scheme into a genuinely ingenious plan to have the poison as a gas sprayed from a quick aerial pass over the fort and then Goldfinger's troops raid the fort just long enough to use a high power laser to open the vault building's door to place a nuclear bomb in the main vault. Then the villains get away for the bomb to detonate and whatever gold survives the blast would be radioactive, and thus worthless, for decades while Auric Goldfinger's own gold's value jumps at least tenfold.

Live Action TV

 * The original Star Trek, when it introduced tribbles, had Spock say that the number of tribbles in a bin, assuming each one has ten offspring and taking into consideration other factors, was 1,771,561. This number is equal to 116, which is to say, it assumes each one has ten offspring without taking other factors into consideration.  The novelization by James Blish changes it to a different number that could plausibly be considering unknown other factors.
