Continuity mistake: When Leigh Anne goes downstairs to see Michael after the first night he stays with the family she is wearing a simple gold cross necklace. When she has to catch up with Mike out on the driveway she is wearing a cross make up of round diamonds. The two necklaces change appearance in same scenes in several places.
Factual error: Just before Michael and Leigh Anne enter the Big and Tall store, they walk past a Georgia Lottery 'PLAY HERE' sign, and several paces later Leigh Anne says, "I have been in Memphis my whole life..." illustrating that it was filmed in Atlanta, GA, not Memphis, TN. (00:32:30)
Other mistake: During the scene in which Michael and SJ are singing and have a wreck, the "Passenger Airbag OFF" light is on. However, Michael is said to have stopped the airbag that wouldn't have deployed. Nothing is stated to show that it would have been faulty.
Character mistake: In the scene where the biology teacher (Mrs. Boswell), looks-over Michael's test paper. There are at least 4 or more factual, spelling, and/or grammar errors on the test itself: Question 5, answer "a" has incorrect grammar. Question 6, uses the spelling of the number 2, as "to". Page 2 of the test, question 3 spells the number "two" incorrectly. Question 4 refers to a previous question about environmental changes that doesn't exist in the test.
Character mistake: During the montage of teachers trying to get Michael up to speed, we see a history test Michael has completed being marked. The question at the top asks where the battle of Waterloo took place. Michael has answered Germany, which has been marked by the teacher as correct. The correct answer was actually answer C, south of Brussels. (00:37:45)keatsmeister
Factual error: When the family eats at Thanksgiving they are watching the Egg Bowl between Ole Miss and Mississippi State which is always played on Thanksgiving. But you can see through the windows that it is light outside and the Egg Bowl is played at night. Even if it was the start of the game, the game starts at 6 pm Atlanta time which is dark by then.Jody Williams
