Factual error: The opening scene of the Skyview collapse takes place on May 16, 1968, according to a newspaper clipping about the tower being closed for repairs as a result of Iris' premonition. During the vision, when the first bodies fall from the sky, the parking valets are listening to "Raindrops Keep Falling on My Head" on the radio. However, that song was written for the movie "Butch Cassidy and the Sundance Kid" and wouldn't be released until October 1969.
Factual error: As the end credits begin to roll, we see Old Sammie play in a concert in 1992. Next to him, a member of his band is playing keyboards on a Roland XP-80 (you can literally read it in big letters on the instrument). The XP-80 came out in 1996. (02:04:00)
Factual error: After showing the sign for DHS headquarters at 3801 Nebraska Avenue NW in Washington, D.C., the next shot depicts a modern glass high-rise as the building. The real DHS Nebraska Avenue Complex is a collection of older brick buildings, not a sleek office tower, making the establishing shot inaccurate to the location shown. The drone shot also shows the building as the DHS headquarters. (00:01:45)
Factual error: In reality, it is illegal to keep a chimpanzee as a pet in Hawaii.
Factual error: When the movie starts, "1964" is shown on the screen. After a scary event, Lorraine goes into labour and gives birth to Judy Warren. The real Judy Warren was born in 1946, not 1964. Later, the movie moves to 1986. The movie shows a young Judy (19-20) with a boyfriend. Judy actually met and married her husband, Tony Spera, in 1979 or 1980. The movie showed them being married after 1986.
Factual error: The film is set in Pennsylvania, but Justine goes into a liquor store that sells beer, wine, and spirits. In PA, beer is sold in package goods stores, supermarkets, and some convenience stores. Wine and spirits are sold in state liquor stores. In PA, you cannot buy beer, wine, and liquor in the same store.
Factual error: Spike is shown having a Power Rangers figure in his bedroom. The only problem is that it's from the Operation Overdrive series, which didn't come out until 2007, five years after the initial outbreak in 2002, isolating the UK from the rest of the outside world as a result.
