Factual error: In an attempt to create a believable 1940s gym, it appears the production crew got hold of many contemporary boxing posters as possible. Most of these were Greeked to avoid mentioning real boxers (such as "Dave Ritlaf" and "John Paropianeo"), but one of these prominently features a "Ronnie Harris", along with a photograph. Ronnie Harris was a real boxer, but wasn't even born until 1948, 7 years after this scene was set, giving away that a poster from the '70s was used. (00:16:08)
Factual error: When driving to meet the Jordans you can see a white car in the distance on the right that is from the 21st century. (04:01:00 - 04:04:00)
Factual error: The game against Bellevue was not at Bellevue High School as depicted in the movie. It was played at the Tacoma Dome as part of the Washington State Kickoff Classic.
Factual error: The onlookers are eating pears in spring. Wrong time of the year for ripe pears.
Factual error: In the Templehoff Airport flyover scene there are Soviet era Antonov An-12 propeller driven aircraft on the tarmac. These were first used by the Soviets in 1953.
Factual error: It's highly unlikely that any military police from another country would be allowed entry into the U.S. to search for a deserter of its military. In any case, the illegal alien would just hide here under the radar until found by ICE or the police and then deported back to his or her country.
