Other mistake: When Alex, Marty, Gloria and Melman are talking together inside the boxes, Alex has three holes in his box allowing light in for him. Melman, Marty and Gloria have that too, but Gloria's box is lying under Alex's and Marty's, so it can't get as much light - but it does.
Suggested correction: When we see the outsides of the box on the ship we can also see little gaps caused by wood planks nailed to the sides of the box so there should be a little light coming from in between to Gloria's box holes.
Gloria: Where are the people?
Skipper: We killed them and ate their livers. Gotcha there, didn't I?
Trivia: When Alex (voiced by Ben Stiller) is taking pictures for the crowd in the beginning he strikes the famous "blue steel" pose from another one of Ben Stiller's movies, "Zoolander".
Question: This applies to both Madagascar movies. Does anybody know why Sasha Baron Cohen (Julian the lemur) never shows his face and is barely mentioned in the DVDs for these movies?
Answer: Sacha Baron Cohen is a very private man; he is rarely seen in public, and when he is in public, he is usually dressed as some of his other movie roles (Borat, Bruno, etc.) He has even mentioned once that he wants his characters to be famous, but he wants to live a normal life, so he is rarely interviewed by press.
