When Jack is making all the wire transfers to the Cayman Islands, the same six names and amounts continuously scroll by.
After Jack gets to the house by the water, he's in a fight that catches a car on fire. Burning tires produce a lot of thick black smoke. But after he rescues his family, as they are walking away from the house, there is no smoke rising from where the car should be.
Jack's message is heard on Harry's answering machine before Beth's message, but Beth supposedly called Harry and left a message first, so Beth's message should have been heard before Jack's.
When Harry answers his cellphone when in bed, its a cam-shell/flip-phone, but he answers it, and holds it to his head without opening it, even though you hear the sound of the flip opening when the phone is out of the camera view.
Jack's home-office Dell LCD Flat Panel doubles it's size a few times.
(at around 58 mins) Jack has taped his makeshift scanner near the bottom of the monitor, and the data appears and scrolls from the top of the monitor. The first 20 or so largest accounts never pass in front of Jack's taped-on scanner.
When Jack goes to the bank at Seatac Airport to authorize the "reverse" wire transfers he would not be able to authorize a "reverse" wire from the bank where he was at. Only the bank where the funds originated can authorize a wire transfer to another institution. Secondly wire transfers do not happen instantaneously as depicted. They have to go through the Federal Reserve. It was late at night in this scene and the Federal Reserve closes at 6 p.m. EST. In Seattle that means that any wire originated after 3 P.M. would not have taken place until the next business day and even then could have taken up to 2 hours.
Andy appears to be quickly cured from an allergy attack to nuts after --only using an EpiPen. He would have to go and be treated at the hospital for full cure, the EpiPen only gives the person more time after an allergy attack. Even if going to the hospital wasn't shown, it would reveal that the family is being held hostage.
The amount on deposit with a bank is not the Bank's asset, rather they are Liabilities.
On the night the family is taken hostage, three scenes from the movie Le vaisseau fantôme (2002) are played out of sequence on television. Only the audio can be heard in the latter two scenes.
When Jack removes the memory card from Bobby's phone, the phone is still turned on. This would not cause data corruption if the card isn't being accessed at the time as the vast majority of memory cards are hot swappable.
The car the secretary drives appears to be an automatic; when she stops the car in front of bobby's church, she firmly pushes the gear lever into "park" which makes the car lurch. If the battery is dead on an automatic, you cannot start it by pushing. Luckily the transmission is a 4 speed manual Hurst floor mounted shifter.
When Jack is driving to work at the beginning of the movie, a radio traffic report states that it is morning, but the Seattle skyline is shown sunlit from the west, indicating it's actually late afternoon.
When starting the secretary's car Stanfield says to pop the clutch which then starts the car. However, several times later the car appears to be being put in Park. However it is indeed a 4 speed manual floor mounted Hurst shifter.
The same close-up shot of hands typing on a keyboard is used twice. Once when Gary is looking at Jack's security file and again when Jack is removing money from Bill's accounts at the airport bank.
When Jack first drives to the bank, we can see a Canada Post truck waiting at the intersection, although the action takes places in Seattle.
When Jack first comes home to find his family kidnapped they are bound and gagged, but you can hear his boy cry, "Daddy, Daddy," even though he has duct tape over his mouth.
When Jack's in the cabin, he crashes through a window covered with plastic. The sound of shattering glass is clearly heard, however if you look at the window after he's gone through it you see is only the plastic, and there is no glass.
When Jack's secretary asks her boyfriend to lend her his phone while he's playing bass guitar in a live band, he has to stop playing to get the phone out of his pocket but the bass line in the music continues uninterrupted.
When Jack is looking into the computer screen in Bobby's office, you can clearly see that it is a still photo shot of Jack reflecting into the screen, not a real life movement shot.
When Jack starts his secretary's car, his left hand is on the steering wheel while his right hand appears to remain on the center console, somewhere around where the emergency brake or gearshift would be on a car with a standard transmission.
The address on the account for the dog's tracking collar shows a Medina, WA address. The only body of water that Medina, WA is next to is Lake Washington. The house that is filmed throughout the movie is clearly shown on the edge of tidal waters indicating that it is not a Lake Washington waterfront home but next to the ocean (or Puget Sound).
Scotiabank (Bank of Nova Scotia, Canada) logo visible on a skyscraper when Jack is on the apartment building roof.
Was there anything to prevent Jack from handwriting a distress note with pen and paper off to his side, beyond the scope of the body camera?
When Jack logs into the router to filter the attempted hack coming from multiple countries, he creates an access list which only would filter a few addresses and allows everything else. His cohort's expression of "That would even eliminate false positives!" is fully false.
In the bathroom scene, Bill Cox is in a stall while Jack (in the next stall) is transferring files. Bill notices and verbally points out that someone entered the bathroom and leaves without washing his hands. When they are done they both leave the bathroom without washing. Even though Bill Cox didn't "use" the facilities he still touched many areas in the bathroom that are touched by people who haven't washed yet after "using" the facilities. The germs he tells Jack about are the same as he transferred onto his own hands.
When Andy is playing Monopoly he rolls a nine but only moves his piece seven times.
