Reese says that he was high when he told Ricky "If you're not first, you're last", and that it doesn't make sense, but when he is driving away from the school he has a bumper sticker that has the quote on it.
Ricky's father tells him at the motel that he was conceived when he was only 17, putting Ricky's father 18 years older, at most, than Ricky. Later that day (in the kitchen), Ricky's father tells Ricky that he is 55 years old, which would make Ricky either 37 or 38. When Ricky gets his drivers license, it shows his DOB is 7/16/71 and the date issued is 7/16/02, which would make him only 31.
At the first race when Ricky and Cal are pit crew members, the entire crew has the American flag on their right sleeve displayed backward. The US Flag Code calls for the stars to face in the direction of motion, which would be to the right on a right sleeve.
During Ricky Bobby's first crash, he's shown shifting gears in an effort to catch up to the Frenchman. He's wearing Silver shoes with a blue Puma symbol and after the crash, while he's running around "on fire", he's wearing blue shoes with a yellow Puma symbol.
When Cal is whispering "Shake and Bake" into Girard's ear, a wedding ring is on his finger, but at this moment he is not married. This happens during the fight between Girard and Ricky when Ricky shows up at the track with a broken arm.
When Reese is trying to get Ricky to 'make friends with the fear', Ricky opens the door to the car and then closes it after seeing the cougar. When Reese tells him to get back in the car, the cougar "unlocks" the door by pulling the lock up, though it was already unlocked.
When five-year-old Ricky steals his mother's station wagon outside the convenience store, the same maroon 1972 Ford Mustang is shown twice. First spinning out from the left as Ricky exits the parking lot (viewed from the store), and in the very next shot, the Mustang swerves again as Ricky navigates the busy street (long view).
When Cal Naughton, Jr calls Ricky, Ricky reaches over to answer the phone behind the cushion and knocks the remote between his body and the couch. A little later, the remote is in his other hand, then it is on his lap, and then back in his hand again.
At the end, the "ME" car when revealed, is powered by a grungy, orange small-block Chevy V8 with a distributor at the rear of the motor. After "borrowing" parts to be competitive, it becomes a small-block Ford V8 with the distributor in front.
When Ricky Bobby's father gets thrown out of Applebees and they are walking down the center of the street, from the head-on shots as he is following his dad, the double yellow centerlines are far apart. In the side, profile cuts, the centerline is a normal double yellow line only about one foot wide.
When Ricky and Jean get out of their cars after the final crash, Ricky clearly has a "soul patch" (facial hair on lower lip). However, when they are running to the finish line, he does not have the patch. When they are waving to the crowd, Ricky has his patch back.
At the final race, when Cal and Ricky are arguing, Ricky grabs Cal. During this whole time, Carly has not been wearing sunglasses, however shortly after Ricky grabs Cal and begins apologising, Carly is suddenly wearing sunglasses.
In the bar, when Ricky and Susan are talking, the table beside them, currently in the foreground, has a tip on it. In the first shot, the bills are lying flat, but in all proceeding clips, the top bill is folded up in the back-right corner.
When Ricky is in the hospital and his teammates are talking to him about how he is not paralyzed and he can use his legs, the collar/neckline of his hospital gown repeatedly changes position around his neck between shots.
During the race where there is a large "Fig Newton" sticker on Ricky's windshield, the wording slopes downward from the passenger side to the driver's side, when viewed from outside the car. This would block Ricky's view. When the camera is inside the car, looking forward, the wording slopes upward from the passenger side to the driver's side, giving Ricky a relatively unobstructed view.
When Reese Bobby shows up at school for career day and is standing at the door of the classroom he is wearing sunglasses. The shot cuts away to Ricky excited to see his dad then cuts back to Reese and the glasses are gone. The shot cuts away to the teacher then back to Reese and his sunglasses are back.
In the Thanksgiving dinner scene (Baby Jesus), the Dominos pizza box between Chip (Ricky's father-in-law) and Cal (his driver friend) changes its position several times. (Watch the logo on the side of the top box facing Chip appear and disappear).
When Bobby tries to win the race while driving in reverse there should have been flaps on the roof. Every NASCAR car has flaps that open up on the roof to prevent them from flying into the air when in a crash. They only open when the car is moving in reverse with sufficient wind speed.
Although NASCAR does allow relief drivers to get in a car after the race is already started. The relief driver must have practiced in a NASCAR Cup car during that weekend at that track of the event. Since Ricky is on the pit crew, he would not have practiced a car and therefore would not be allowed to get in the car for his first race.
NASCAR did not implement the double file restarts for lead lap cars until midway through the 2009 season. Since Ricky Bobby and Jean Girard were both still on the lead lap, Ricky Bobby would have had to line up behind Girard since he was in second place when the caution flag came out. Ricky would have been black flagged for lining up that way, meaning he could not have won the race, even if he had crossed the line before Girard.
During the restart when both Jean Girard and Ricky Bobby are the only 2 remaining cars with 6 laps left, they start side-by-side. In NASCAR, all lead-lap cars restart single-file, and with 10 or fewer laps left, all carts restart single-file, regardless of being on the same lap or not.
When Reese goes to pick up the two Talladega tickets, the sign at the vendor window says "Saturday Tickets." In reality, a Sprint Cup race (the circuit Ricky would have been racing in) would only take place on Sunday, especially at Talladega.
When Ricky and Cal execute "Shake and Bake", they downshift before pulling out of line. With the exception of restarts, and entering and exiting pit road, shifting is not necessary during the race. Also, Ricky was single-handedly passing multiple cars at Talladega. With today's air packages and plates, passing one car alone is a feat that rarely occurs.
Ricky was fired from Dennit Racing but before the last race it looks like his uniform still has Dennit Racing on it. However, a closer look shows that the wording has been at least partially removed, but that the stitching is still visible.
Twice in Ricky's mother's kitchen, Texas Ranger mouths Walker's words. Although this is a common actor's mistake, it makes sense in this particular context. These two are always planning and thinking together, so the idea that they can anticipate each other's every word is quite fitting.
Ricky Bobby said that he is "El Diablo" and explains that "El Diablo" is a fighting chicken. In Spanish, "El Diablo" means The Devil. It shows Ricky Bobby doesn't know Spanish. As the film is a comedy, the film makers meant for it to be a joke.
When Ricky Bobby is being interviewed by a news crew, one of them is holding a Panaflex 35mm motion picture film camera - obviously, the film's cinematographer. Panaflex cameras are not, nor have they ever been, used to film news.
When they are supposed to be leaving the speedway in the evening to "go get kicked out of Applebee's", they turn right and speed away from the main entrance. They are actually heading east on the roadway (Speedway Blvd/AL Hwy 399). By the shadows, it was actually shot sometime in the morning.
There are two race cars shown as Dodge Intrepids, Jamie McMurray's car and the yellow #22 Caterpillar car. NASCAR switched to Dodge Charger in 2005, although some team were still using the Intrepid. In the final race at Talladega the yellow #22 Caterpillar car is shown as a Dodge Intrepid but with Dodge Charger logos. At the same race, Jamie Mcmurray's car can be seen as a Dodge Charger stock car during the big wreck.
During the long crash that ends Jean Girard and Ricky Bobby's race, both cars lose most if not all of their wheels, as they are visibly attached only by their safety tethers. After the wreck, however, both cars have all their wheels in place.
During the climatic crash, when Ricky Bobby and Jean Girard's cars are tumbling and crashing in slow motion, the interiors of the cars are plainly and repeatedly visible, revealing no engines, no transmissions, and no car parts whatsoever. These crashed vehicles were clearly only car bodies with wheels cosmetically attached.
