Factual error: Airbags which deploy and stay inflated. That's not how airbags work, they deflate immediately.

Factual error: IP addresses are 4 groups of up to 3 numbers each, maxing out at 255 - it's a fundamental limitation of the technology. But IP addresses in movies are often shown as something like 564.100.432.165, which is impossible. This isn't like movie phone numbers all starting with 555, because that's still a feasible phone number, just with a "movie" area code.

Factual error: Often when bombs are shown falling, they're depicted with a distinct whistling sound. Two problems there. Bombs don't inherently whistle - some bombs in WW2 were specifically fitted with whistles for the psychological warfare element, but the vast majority are silent. Secondly, the standard noise heard from the ground, a high pitched whistle slowly getting lower, is wrong. The doppler effect, whereby a sound changes as it moves closer to someone hearing it, means the pitch heard would increase, not decrease, as a bomb falls towards you. The sound most often used in movies/TV shows of a whistling bomb is what the pilots dropping the bomb would hear, not the people it was falling towards.

Factual error: People taking cover behind very small / flimsy things, like car doors or wardrobes, dozens of bullets being fired at them, but they emerge unscathed.

Factual error: Someone gets punched in the face or otherwise knocked out and comes around hours later, then goes on to pick up where they left off as best as possible and forget the incident in about 30 seconds. If you've been unconscious for hours you've got a traumatic brain injury and need medical attention, you won't be hunting down your assailant any time soon.
