Corrected entry: When Lara's test results show her diabetes is dangerously out of control, she would not have been rushed to the hospital without first running a very quick and simple blood sugar test. Diabetics routinely test themselves several times per day, so the prison medical office would already have the test equipment on hand.
Corrected entry: After John makes the decision to leave their son behind (with his parents) in order to make their escape, Lara attempts to kill herself by jumping out of the SUV. It is nearly impossible to open a vehicle door while the vehicle is moving faster than say 20-30 mph because of the wind resistance. They are cruising at highway speed, yet she simply flings the door open with ease.
Corrected entry: In the scene where John and Lara and their son are at the airport and seem to be headed for some destination (ergo leaving the United States), they are going through what seems to be U.S. immigration. Correct me if I'm wrong, but doesn't U.S. immigration come into the picture when you are entering the country? The people that would be looking at passports upon exit are airline people.
Corrected entry: When John starts following the medical van for the first time, you see the van from the front as it turns onto the road where John awaits it in his car. The van's number plate is missing.
Corrected entry: Near the beginning of the movie, Lara uses a very large syringe to inject a huge (and likely harmful) dose of insulin. Insulin is used in very small doses typically from a small syringe, so if using a large syringe, the plunger would barely be pulled back.
