Factual error: When Nicole Kidman is giving Tom Cruise a Neurological exam she does what she says is called "The Vavinski sign" (running the back of a reflex hammer along foot sole). It is actually called the Babinski sign, a reflex that can be the indicator of brain or spinal cord damage. Big toe goes up and other toes spread = bad (or just ticklish). Nothing = okay. Toes go down = okay. Even professionals (note I'm not one) have trouble interpreting this one, and you cannot get accurate results by doing it on yourself, folks. (00:57:55)
Factual error: A Nascar driver can't go from the pits, to top speed, and pass 43 other cars in only three laps. The drivers get to top speed very quickly and they do not have an extra gear to shift into, like Cruise did when he decided to just run through all 43 cars to first place. Cruise manages this awesome feat at the end of the race. Amazing racing.
Continuity mistake: In the final Daytona 500 after Cole drives through the smoke and catches up to Wheeler, Cole is running 3rd behind Wheeler and the 26 Brett Bodine Quaker State car. After a cut away, Cole is 3rd behind Wheeler and the 33 Skoal Harry Gant car. When the wreck happens Cole crashes into the 33 car, but the 26 car is the one that spins to the inside.
Factual error: I don't know many men who can jump out of a 150 degree race car after 500 miles, not have anything to drink and immediately have a 100 yd footrace with their crew chief. No matter how many drinks of water a driver might receive, he is physically and mentally exhausted after driving 500 miles at around 200 mph inside a 120°F-140°F racecar which he has used to dance around within a tightly packed group of cars.
Audio problem: At the Daytona 500, Cole bumps the race leader (Wheeler, I believe) and says "Remember me?" His lips don't move.
Continuity mistake: In the pit lane before the last race at Daytona, Harry has the hood up on Cole's car. The air cleaner housing is the cowl air induction type commonly used on NASCAR race cars. Seconds later when Cole walks by and Harry explains that they had to change engines, the air cleaner is a round chrome plated type commonly used on street engines.
