In the office of the recruiting service when they guy hands Tom Lemming the DVD of Michael Oher, if you look at the magazine that the DVD case is sitting on you will see a picture of Bryce Brown in the Army All-American game. Bryce didn't sign with Tennessee until 2009 which is when he graduated and the film is supposed to be set in 2003-2004.
The car driven by Leigh Anne Tuohy is a BMW 750LI. However, the BMW 750LI wasn't available until 2006, and the movie takes place in 2004. The '06- '08 models have a face-lift compared to the prior models.
In the very beginning when Michael Oher's friend's dad is first driving him to Wingate, it must be late 2003 or early 2004. As they drive past the lemonade stand, a Volkswagen EOS is visible, which wasn't introduced until late 2005 as a 2006 model.
They say Michael is in the 98th percentile for "protective instincts." However, this means he scored better the 98% of all the students who have taken this test, and not that he reached 98% of the total score as Leigh Anne says later.
The quote on the archway at the Christian School attended by Michael Oher and S.J. Tuohy is a misquote of Scripture. The second line ("With God all things are possible") is correct, but the first line should read "With Man this is impossible" not "With Man this is possible". The original context being Jesus' reply to his disciples when they realize how difficult it is for a rich man to enter the Kingdom of Heaven, recorded in Matthew's gospel.
During the first game, after a play, the down marker is seen being changed from a 2 to a 1, meaning that that would have been the second play ran. The team scores two plays later, yet the coach says they scored in three plays, when in actuality it should have been four.
At Thanksgiving dinner, while the family watches football, Leigh Anne Tuohy is in the kitchen with the food. Leigh is holding a glass of wine. In one shot, she starts to take a drink. In the next shot, the glass is nowhere near her lips.
In the Thanksgiving Day scene when Leigh Anne Tuohy tells the family to come eat the first clip shows Sean Tuohy serving himself mashed potatoes and green beans then the clip switches and shows Sean reserving himself mashed potatoes but no green beans.
When Leigh Anne Tuohy discovers that Michael Oher is leaving after staying 1 night, she is wearing a skinny cross around her neck. When she walks outside to stop him, her necklace is the round cross. In the next scene, it switches back to the skinny cross.
The morning following Michael Oher's first stay at the Tuohy house, Leigh Anne Tuohy puts on a grey sweater with a noticeably pointed collar. When she moves downstairs to look for Mike, the same grey sweater collar changes from a pointed collar to smooth rounded neckline.
In the scene where Leigh Anne Tuohy is having lunch with her friends and they are discussing Michael Oher's appearance on the Touhys' Christmas card that year, the woman who says that Michael is a potential threat to Collins Tuohy is wearing a large necklace made of gold medallions. The medallions change their positions as the camera angle changes back and forth from Leigh Ann's POV to the friend's POV. Sometimes they are lying across her throat in a flat position and at other times they are twisted slightly, changing back and forth from flat to twisted for no apparent reason.
Early in the movie, when Michael Oher is riding in John Hamilton's car on their way from West Memphis to Wingate Christian School, a real estate sign with an area code 770 phone number can be seen through the car window. The phone number belongs to a real estate agent in the greater Atlanta area. (The phone number is 770-683-1800, which belongs to Josey Young & Brady Realty in Newnan, GA.)
The movie's introduction credits former New York Giants linebacker Lawrence Taylor with making the left tackle the second most important and highest paid position in the NFL after quarterback. That is an oversimplification, necessitated by the movie's focus on Michael Oher. The book divides its narrative evenly between the evolution of offensive tackles in the NFL and Oher's story. Among the top 10 highest paid players in 2008, only two were quarterbacks, and one, Flozell Adams, was a left tackle. As the NFL's first dominant blitzing linebacker, Taylor forced NFL coaches to adjust their formations, personnel, play calling, and schemes. However, left tackle was already a key position, and Taylor's impact went beyond one position. The right tackle position became just as critical to NFL teams due to a large number of superstar left-handed QBs, including Stephen Young and Mark Brunell. Oher started at right tackle during his 2009 rookie season for the Ravens, except when he filled in for injured left tackle Jared Gaither.
The Tuohys watch an Egg Bowl game (Mississippi State vs. Ole Miss) during the daytime. The game shown is the 2003 Egg Bowl at Mississippi State, as evidenced by Eli Manning as Ole Miss QB, Ole Miss wearing white "away" jerseys, Mississippi State's white helmets with maroon numbers (worn during the 2003 season finale), shots of fans in rain gear (the game was played in a downpour), and being televised by ESPN (who last televised the Egg Bowl in 2003). That game kicked off at 6:30 PM.
In his first game, after the kickoff before their first play, you can see the scoreboard clock behind the team and the clock is running. Clocks don't restart after a kickoff until the next play has started.
After Michael Oher and S.J. Tuohy are in the accident, we see S.J's mother rush over to the ambulance where he is waiting on a stretcher without a C collar on. If you are being transported to the hospital by ambulance after a car wreck, you are almost always immediately put in a C collar, in case of neck or spinal injury. Since he had struck the airbag AND had facial injuries, he would have been put in the C collar right away.
Quinton Aaron, who played Michael Oher, is 6'8", but the real Michael Oher is 6'5". The 3 inches of "extra" size help the filmmakers dramatize (among other things) how out-of-place Oher looked at a school full of mostly average-sized white kids.
In at least one closeup of Michael Oher in his football uniform, his mouthpiece is hanging from his facemask upside-down compared to the way most players hang it (e.g. the guard would be facing down when he put it in his mouth instead of up). Also, the mouthpiece is clearly brand new and has not been shaped to fit Quinton Aaron's mouth.
When Leigh Anne Tuohy invites Big Mike to stay for Thanksgiving dinner, all the trees in their yard are full of green leaves. In the following scenes when Leigh Ann takes Michael Oher shopping, all the trees on the street and reflected in the windshield of her car have green leaves. In Memphis in November, all of the trees would either be turned fall colors or would have already lost the majority of their leaves. The scenes was clearly shot during the spring or summer.
In one scene, the TV shows Tennessee beating Clemson. Tennessee is playing Alabama, not Clemson, as you can see by their helmets, and color of uniforms. Both Clemson and Tennessee wear orange. Alabama wears red.
