Visible crew/equipment: When Miles Dyson, president of Cyberdyne, is talking to Danny Dyson and John Connor; whilst they are all looking towards the production line of liquid metal, you can see that the bodypack transmitter falls/dangles off under Miles Dyson's suit jacket. And as he steps off the shot, you can see him reach under with his hand to attempt to hide it.
Terminator Genisys (2015)
1 visible crew/equipment mistake - chronological order
Directed by: Alan Taylor
Starring: Arnold Schwarzenegger, Jason Clarke, Jai Courtney, Emilia Clarke
Factual error: During the opening narration Kyle Reese states that Skynet attacks humanity on August 12, 1997. In the shot of missiles decimating San Francisco, multiple 2005-present Toyota Priuses, Dodge Chargers and other late model cars are seen.
Trivia: The line "come with me if you wanna live" is said by Sarah Connor for the first time in the franchise.
Question: If John Connor and the resistance are so good at reprogramming Terminators (They have done it 3 times during the series), why don't they just use them to help fight the war? Continuously sending them back in time may have kept Connor alive, but has achieved little else.
Chosen answer: As long as Skynet kept sending other Terminators into the past to kill John Connor before he became the leader of the human resistance, it was necessary to keep sending reprogrammed Terminators into the past as well so that the timeline would not be altered, thus resulting in a Skynet victory. While it is possible that John and the resistance may have used reprogrammed Terminators to help them in the future, this was never depicted or otherwise mentioned within the film series.
Suggested correction: That 1997 was from another timeline before the events in Terminator 2 altered history. It's possible those models may have existed earlier in that timeline than in our world.
This is assuming too much about the alternate timelines. There would have to be more concrete evidence that such things would be altered in said timelines. Also, considering that timeline is supposed to be what took place from Terminator 1 in its own separate timeline, we would go still by our own following the events of it leading up.
