Factual error: When the house explodes, there is a massive explosion and fireball that creates a pressure wave strong enough to send Brian flying into the van. However, not a single window breaks on the houses just feet from the explosion. (00:15:40)
Factual error: At the beginning, the film is set in 1995 only for a brief few minutes. Then, it goes on to say "15 years later." This brings us to 2010. In 2010, the latest iPhone was the 4. However, throughout this film, nearly every iPhone shown (quite a few) appears to be an iPhone 5s. This is obvious by the rectangular body with fingerprint sensor. In addition, in some places the latest iPads are used, the iPad Air 2 and the iPad mini 3 - These were released in 2013 and beyond. Finally, although I am not 100% sure, towards the end of the film as the woman steps in to the car for the final time on the hill next to the boat, it appears she is wearing a gold Apple Watch or other smart-watch which was released later than 2010.
Factual error: At the beginning when Kate enters the bedroom and is shot at, the hole made by the shotgun could only be made by slug ammunition, but you see buckshot around the hole. Buckshot at that range of about 12 to 15 ft. would not have made a center hole anywhere near that size. (00:03:20)
Factual error: Towards the end of the film, where St. John is trying to escape with Kim in his private jet, they are apparently attempting to take off from Santa Monica airport. When the camera shows the aircraft beginning its take off roll, the runway markings show that they are using runway 05L to take off from, however, the two runways available at Santa Monica airport are 03 and 21.

Factual error: Richardson's watching the World cup final (1966) way way before Reg got married to Frances (1965).
Factual error: In the early part of the movie, there is a shot of the outside of Triple O's bar. The scene takes place in 1975 and "Coors" is advertised on the outside of the bar. Coors beer was not available in Boston/East Coast in 1975. It was only available from the 1980's.
Factual error: When he is in the restaurant and looking at the security feed, he does a who command when it should be "whois". Also the IP is incorrect - the 3rd octet is 265, despite the maximum possible value being 255.
Factual error: Like in the previous movie, the female lead introduces herself formally as Detective Maggie Price, from San Francisco Police Department. Where the correct rank is "Inspector."
Factual error: For being set in the spring in San Francisco, the trees (look at Maggie coming back home in the intro) are rather barren and there are dead leaves in the grass.
Factual error: At the beginning of the movie when Danny Glover is sitting at the chessboard, the pieces are lined up wrong on both sides of the board. If Danny has the white pieces, the king should be on his right. The black king should be on the opponent's left.
