Factual error: On the plane, while being escorted by FBI agents, Frank Jr sees New York's LaGuardia Airport and says, "There it is, LaGuardia Airport, runway 44." A runway numbered 44 is impossible. No runway can be numbered over 36 because there are 360 degrees in a circle. (01:58:25)
Factual error: An old man appears with children following him. This is supposed to be pedagogue Janusz Korczak. It appeared as if he was just wearing a suit and a Jewish arm band. In the Warsaw Ghetto, Mr. Korczak never wore an arm band and wore his WWI Polish Army Uniform, both as acts of defiance. He was beaten and almost put to death (he had connections) for not wearing an arm band so having one on in the movie is inaccurate.
Factual error: Chuck and Penny are seen drinking Rolling Rock beer in clear glass bottles. But Rolling Rock beer has always come in green glass bottles.
Factual error: The issue of "Guideposts" shown by Crane's interviewers is from the early '90s.
Factual error: Frida is shown watching King Kong when she goes to New York. It is well known that the movie was made in 1933, but later we see on her mother's grave that the year is 1932.
Factual error: Cheryl works in the Navy Exchange bookstore. In the United States Military(all branches of service) ONLY civilian employees work in the military exchanges, which are small retail stores for military and their family members.
Factual error: Whenever Steve Coogan is driving his old brown car during the 70s and 80s, you can look out of his windows and see cars that weren't made then, even some with current registration plates on, either driving past, or parked up in driveways, or on the side of the road.
