Trivia: Sylvester Stallone originally exited this film in 2017 over creative differences with producer Avi Lerner. Arnold Schwarzenegger exited as well in solidarity with Stallone. The film ended up being shelved for several years until Stallone returned, albeit in a much smaller and final role. Schwarzenegger, as well as other key actors from the franchise, ultimately did not return.

Other mistake: After the first guard at the chemical plant is sniped, the second guard goes to check on him and is surprised by the sudden appearance of an attacking helicopter. Helicopters are extremely loud, and flying as low as it was depicted would also vibrate the ground and the building. There's no way it would have been able to sneak up on the guard like that.
