Corrected entry: When the crates containing the animals falls off the ship, you see the crates become completely submerged. There are holes in the crates so the animals can breathe, but no water whatsoever gets into the crates. Also, when Alex looks through the holes, you can see large waves in the sea. In the time it took for the crates to reach the island at least one wave would have crashed over them, causing water to get in.
Corrected entry: If Madagascar has plenty of fresh water, why are the animals still drinking sea water at the end of the movie?
Corrected entry: The animals talk about going to Grand Central Station (in New York). When they get to the train building the sign on the building says "Grand Central Station" but the actual building says "Grand Central TERMINAL." Grand Central Station is the subway connection. Note that the website of the building is http://www.grandcentralterminal.com.John Pilge
Corrected entry: The Giraffe is being transported in a crate which says 'Giraffe' with an arrow pointing to it in order that people know which way is 'up'. This piece is later used as a makeshift headstone for the Giraffe's 'protest' grave on Madagascar. On this piece the arrow is now pointing away from the name towards the grave, in other words on the crate the word would now have been displayed upside down.
Corrected entry: When the lion, giraffe and hippo get on the train, look at the giraffe's rear legs. One of the tissue boxes comes off. However, when he's sliding around Grand Central Station, he has it back on.
Corrected entry: When all the animals go to sleep, there is a big clock showing 9:25. The hour hand is pointing directly at the nine, however the hour hand of a real clock would be positioned between the nine and ten because it's almost nine-thirty.
Corrected entry: No ship in the world could go to the Antarctic from Madagascar and back within 24 hours.
Corrected entry: When the penguins arrive to Antarctica, in the Spanish version (dubbed) it says on the bottom of the screen "Antártica". It was written wrong, since Antarctica in Spanish is written "Antártida", with a D, not a C
Corrected entry: When the animals are on the boat, they say that only the monkey can read. However, when they are in Madagascar the giraffe writes out his Will in English.
Corrected entry: There is no possible way that the four animals could float to Madagascar from the boat if they were going to Africa from New York; Madagascar is on the exact opposite site of Africa as the Americas.
