Factual error: When Secretariat crosses the finish line, that finish line pole is not from Belmont, that finish line pole is from Keeneland.

Factual error: After sleeping in and being late for practice, Jack is driving to the gym. It is supposed to be morning yet the shadows made by the sun show the sun is setting over the ocean and therefore evening.

Factual error: The three scorecards of 95-94 for the Dixon vs Balboa fight could not possibly be scored that way for a ten-round professional fight in which so many knockdowns occurred. Each fighter went down multiple times, which would've resulted in a much lower set of numbers using the ten-point-must system enforced in Nevada (and pretty much everywhere else). (01:30:25)

Factual error: In one scene Cobb and the sportswriter doing his biography are driving across the country to get to the baseball Hall of Fame. They are stopped next to some railroad tracks fixing a flat tire, and a train goes by that has Burlington Northern markings (BN). Burlington Northern didn't come into existance until ten years or so after Mr. Cobb died.

Factual error: During the opening credits, Jack Lemmon walks past two "sailors" in dress whites. If they were actual sailors, they would have rate insignia on the left sleeve, service ribbons on the left breast, and a rocker patch on the right shoulder seam.

Factual error: The movie largely takes place in California during the 1990s. California's mandatory seat belt law went into effect 1/01/86. When Mickey was driving Kyd to the cemetery, they were not wearing seat belts. Also, Kyd was 8 years old at the time. Although legally permitted to ride in the front, it is advised that kids sit in the back seat for safety. Considering Lyla was recently killed when a driver ran a stop sign, Mickey should have been more concerned for Kyd's safety as a passenger. (01:12:58 - 01:15:05)
