Character mistake: After Edmond changes his identity to become the Count of Monte Cristo, he is addressed several times as "Your Grace." "Your Grace" is a term of address used when addressing dukes and duchesses. He should have been addressed as "Your Excellency", which is the address given to counts and countesses.
Character mistake: When Marisa boards the bus in the beginning of the movie to take Ty to school, she is on a Bx1 bus on the Grand Concourse and 173rd St going southbound. However, it is obvious Ty attends PS 33 on Fordham Rd and Jerome Ave in the next scene which is north of their location. It doesn't make sense at all for her to get on a southbound bus when she should be on a northbound bus. The 4 train is shown in the distance going uptown while she is walking up the stairs to the Grand Concourse. Why didn't she just take the train uptown since it stops at Fordham Rd in front of the school but instead she chose to get on a downtown bus? She is basically going in the opposite direction in real life.
Character mistake: When Thunder Jack first arrives at the cabin to buy the dogs from Ted, you hear him yell whoa to stop his sled dogs. After Ted is sprayed by the skunk, Thunder Jack is explaining the proper way to stop the sled dogs and says that you yell "hook and brake".
Character mistake: After George reads his speech to Lucy, she says it was fine except for "the split infinitive near the end." There was no split infinitive. (For example, "to boldly go" is a split infinitive; "to go boldly" is not.) (01:29:00)
Suggested correction: She was joking. She was trying to find something to criticise in his speech because she was still angry so she made something up.
Character mistake: There is a typo on one of the monitors. "human PREformance enhancement" instead of "human PERformance enhancement" (00:16:52)
Character mistake: When Slim is at Mitch's other house, she opens the box to cut the phone wires. This isn't necessary because the wires are coming out of the bottom, so there's no need to open the box.
Character mistake: When the Rohirrim are preparing for the Helm's Deep battle, a man is shown sharpening a sword on a grindstone. He is doing it wrong, but it is the way that most people think is the right way. The stone should be spinning so that the blade is "shaving" it, even though that seems like it would dull the edge.
Character mistake: Throughout the whole movie Bell is left-handed taking tests, throwing baseballs, and everything that he does. As an adult he's right-handed.
Character mistake: When Taj is getting ready to give Naomi a massage, she tells him she likes the song on the stereo. Taj replies "It is the White Barry" (meaning Barry White). It's actually a song called "Stumblin' In" performed by Suzie Quatro and Chris Norman.
Character mistake: When Ben and Stephanie are studying, she repeats the stages of mitosis (which should be prophase, metaphase, anaphase, telophase, with minor differences in the way textbooks divide them) out order; anaphase, metaphase, interphase, prophase. She is supposed to be an A student and Ben, who is also smart and reading from the notes and textbook, says she is right. (00:18:55)
Character mistake: Although great care was taken to duplicate Bob Crane's distinctive hairstyle for Greg Kinnear, Bob Crane's hair was actually parted on the left. The makeup department for this film parted Greg Kinnear's hair on the right, producing a mirror-image of Bob Crane's hairstyle.
