Factual error: When Joe and his girlfriend, who is also Albert White's mistress, walk through the hotel room kitchen, that whole kitchen, is not a 30's era kitchen. It even has a convection oven and a blast chiller, pan racks, etc. that are more from this time.
Factual error: Viggo is "playing" the bagpipes on the wrong side. They should be under his left arm, not his right. He is also not blowing hard enough to make the required sound. They sound good, though.
Factual error: There would be no room for a thumb drive inside of a real Rubik's Cube due to the way they are constructed. When dismantled, the individual moving parts are quite small. It would certainly be possible to construct a facsimile of a Rubik's Cube that would have enough room, but it wouldn't be a fully functional puzzle the way it was in the film.
Factual error: The presidents of South Africa, South West Africa and the Rhodesias all object to Seretse and Ruth's marriage. But the head of state of all these countries and territories at the time was King George VI. None of them had presidents.
Factual error: When the characters are drowning on stakes in the ocean there is a modern yacht in the background.
Factual error: In the wedding and arrest scene the U.S. Customs Service officials have police attack dogs. The U.S. Customs Service only has drug detection dogs. (01:57:00)
Factual error: During the scene when Ed the I.T. guy is working on his laptop to fix the problem with the presentation, his laptop is sitting on top of a couple of Cisco network switches with cables connected to them. The ports on the front of the switch where the cables are plugged in would have flashing lights on to show power and connectivity, as well as lights on the left-hand side of the device as we are looking at it, no lights are present which suggests it is not powered up and connected to anything.

Factual error: The nearest tube station to Wembley Stadium is Wembley Park or Wembley Central and not Park Royal at all.
Factual error: When Chiron is speaking with the social worker after being assaulted by Kevin, the social worker urges Chiron to press charges. It is the government who decides to press charges, based on evidence gathered by the police, including witness and victim statements. Crime victims do not decide whether or not to press charges. (01:02:20)
Suggested correction: It should be noted the term "press charges" in this case is meant to denote that a victim of a crime reports the crime to the police (as in file a charge against a person to the police), not the legal sense of pressing charges in court. Plus, victims of crimes can pursue a civil case against a criminal.
Factual error: I'm not 100% on the make of the bolt action rifle Lee is carrying but I know it contains an internal magazine of maximum 5 bullets. She opens the bolt, and no empty shell casing flies out, and for some unknown and stupid reason loads only one round into the chamber. Single shot bolt action rifles are usually very antiquated and hers isn't, or they are very large anti-material rifles with huge calibers of .50 BMG like the Steyr. (01:13:00)
