Factual error: During the scene where everyone runs outside, the Statue of Liberty head crashes into the street. The head is scaled too small and its size can be compared to the people taking pictures. In real life the statue head is large enough for people to walk into (17' from chin to cranium).frecklejam
Factual error: The dying colonel opens the bomb bay doors, and drops the "little man" atomic weapon on the island, destroying the flying reptiles. In fact, the bomb and the fusing assemblies were transported to Tinian by separate methods. No one in his right mind would have loaded a FUSED atomic bomb into a B-29 to transport it to Tinian.
Factual error: A woman is shown receiving electroshock treatment ("ECT") in a hospital scene which took place in 1928. Although chemicals were used to induce seizures in psychiatric treatments at the time, the use of electricity for the purpose was not discovered until 1937 and not used in the United States until 1940.
Factual error: When Meryl Streep is walking outside and talking to Mrs. Miller about the potential abuses of her son, you can see a basketball court in the background and on the court is a 3-point line. The movie is supposed to take place in 1964 and the 3 point line wasn't introduced until 1979/1980. (01:10:20)steven_frankel
Factual error: At the end of the film, Wyatt and McQuarry each take a briefcase containing $5 million dollars. $1 million dollars in $100 dollar bills (highest denomination in circulation) weighs approximately 22lbs = 110lbs for $5 million. $5 million in $100 dollar bills is also approximately 3445 cu. in. in volume. This would not likely fit in the cases they are carrying, and would not be as easy to carry as they are.
