Factual error: For a baseball movie, you would think they would have known the rules of the game better. There is a scene in which Henry uses the "hidden ball trick" to pick a runner off of first base. He stands on the rubber on the mound with only the rosin bag in his hand while the first basemen holds the ball. It is a violation for him to stand on the rubber or straddle it without the ball in his hand and is called a "balk". Technically the runner should have been awarded second base.
Factual error: When Howard is running after the bouncy ball he is on the second floor of the Mall of America, however, you see him run through the LEGO store which is located on the lowest floor of the Mall of America, which is impossible if he was on the second floor before.

Factual error: Near the beginning of the film there is a map of Europe with the countries coloured in using their respective flags. Great Britain is coloured with the Union Jack (Union Flag) pattern but so is the Republic of Ireland (Eire). The Republic of Ireland is not part of the United Kingdom (the political state) or Great Britain (the geographical term for the island), only the British Isles - they are a separate country and the Union jack is not their country's flag. Only the north or the Irish landmass (Northern Ireland) and Britain should show the Union Jack. If they are using an "old map" it would have to be very old, before the 1920's.
Factual error: The display on John Spartan's cryogenic reads, "August 3, 2032," which will fall on a Tuesday. Later that same day, Huxley says to Warden Smithers, "It's a beautiful Monday morning" (00:11:30 - 00:12:15)

Factual error: When Dave is at the Yankee game and he is telling Linda he wants to marry her from the field, it is impossible for his voice to ring throughout the whole stadium without a microphone (even though it echoes as if he were using one.). Similarly, he wouldn't have been able to hear Linda when she shouts "I'm over here." (01:26:30 - 01:27:45)

Factual error: One of the main characters has a Harley Davidson. The movie is supposed to take place in the fifties. The Harley had an electric start primary cover which wasn't made by Harley until 1965.
Factual error: Cher complains that Astroturf is going to ruin baseball. Mermaids is set in 1963 when Astroturf was still being developed under the name Chemigrass. It wasn't christened Astroturf until it made its world debut on the floor of the Houston Astrodome in 1966.
Factual error: When animated Giselle begins to sing and brushes her hair, the reflection of her "one true love" is visible in the mirror. Problem is that its image is not reversed in the reflection. (00:02:00)
Factual error: At the end of the film, when Ramu is on the Sally Jesse Raphael show, even if it was being broadcast live in New York, it certainly wouldn't be broadcast live in India for his family to watch. Also, India is 9 1/2 hours ahead of New York. If Ramu's family are watching the show when it's daytime in New York, it's awfully light outside!
Factual error: When M and his entourage arrive at Bond's estate, their cars are surrounded by sheep. They then drive on down an unsurfaced road to Bond's house, past a pride of lions he keeps on the grounds. A series of sweeping overhead shots shows us that it is all one huge field, with no fences or the like. Those sheep aren't going to last very long.
Factual error: The "whaling boat" is too small to function as such. It isn't large enough to hold a fin, let alone disassemble a humpback whale.
Factual error: The car Flounder drives is a 1964 model, built beginning late in 1963, but the events of the movie take place in 1962. (00:45:40 - 01:08:25)
Factual error: At the end of the movie, they show a bunch of ducks flying. Those are not ducks, they are geese.
Suggested correction: This was intentional. This is a mostly Minnesotan team and the team is going home. While geese are technically speaking not ducks, they are the state bird of Minnesota and fly in a very similar manner to ducks. This was meant to be a symbolism of them going home to their state.
