Character mistake: At the beginning of the movie, the German sub gets surprised and severely damaged by a destroyer. The sonar man first notices the enemy destroyer approaching, but only a short time before the destroyer is already literally on top of the sub. German sonar at the time had the capacity to detect ships up to more than 7 miles away, so the sonar man really had to be asleep at his sonar station not to notice the destroyer approaching.

Character mistake: When the biologist guy talks about writing code for DNA he names the four codes as A, G, T, P, when they are actually A, G, T, C.
Character mistake: When Maximus is talking to Marcus Aerelius, he mentions that his wife has black hair. But in the scenes where we see her, she actually has brown hair. (00:24:40)
Character mistake: Those are the most haphazardly secured cases of nitro I've ever seen in a movie. Couldn't they spare a shoelace or duct tape to secure the top?
Character mistake: When Carolyn first addresses Imam, she quite obviously pronounces his name "ell-mom," as though the capital I in his title were a lower-case L. It should be pronounced "ee-mam". We distinctly hear Ali call out his name in this fashion after the ship crash lands on the planet.
Character mistake: When Jenny McCarthy goes to the office to meet the director. She's calling out his name to see if he's there & calls " Roman.......Ronin.......Roman". (00:23:15)
Character mistake: The American flag at the New Orleans Mardi Gras is hung the wrong way on the building.
