Factual error: In the beginning of the movie, we see one of the two journalists playing "The Game" in a Game Boy. The other journalist says that the game is available in cartridges and floppy disks. The problem is that the guy playing the game doesn't even has a cartridge inserted in the Game Boy. It's impossible to play ANY kind of game in a Game Boy, if the Game boy doesn't have a cartridge inserted in it.
Other mistake: The Russian flag in the Russian commander's office is upside down.
Continuity mistake: When the group is arriving in Moscow the plane shown during the landing is an Ilyushin Il-62, with four engines on the tail. When they exit the plane and are greeted, you can see an engine under the wing of the plane.
Continuity mistake: During the car chase scene near the end of the movie when Connors jumps on to the black car the windshield is only slightly lowered. Later during the chase the gap is much bigger and when we see Callahan struggling in the back seat it's lowered all the way down. Also, Connors grip on the car keeps changing between closeups and far off shots.
Factual error: Following the incident with the microscope, the Russian Forensic Scientist is afraid she will be sent to Chernobyl - Why? Since the breakup of the USSR, it's in a different country (Ukraine), so the Russian Authorities are highly unlikely to send her there.
Continuity mistake: When Lt. Talinsky and his fellow Russian officer arrive to the warehouse in the yellow car, we see Talinsky in the passenger side of a left-hand drive car and in one shot when the car is spinning, he's now sitting in the driver side (as if the film was flipped). We also see shots of the car with the window rolled up and close up shots of the window rolled down.
Continuity mistake: When the American and Russian police officers arrive at Konali's warehouse in the police van, shots inside the van you can see the window curtains closed, even the back one. On outside shots, some of the curtains are opened, most noticeably the back one. The clearest example of this is when the van is spinning out of control.
Other mistake: When seeing the order form to "Lottsa Gameski", there's a lot of information that doesn't make sense, not including the fact they add "ski" to the end of a bunch of words. The "ship to" address is incomplete and the "order date" is 92/15/94.
Continuity mistake: When the Commandant Rakov is playing the Gameboy, it's in the off position.
Factual error: When we first see Konali, he holds up his snake and we hear the distinct rattling sound that only a rattlesnake makes. However, he's not holding a rattlesnake of any kind.
Answer: They are not related. It is a coincidence.
