Factual error: Renato and Asher could not just fly from the USA to Mexico; they'd need permission to fly and crossed a border without a passport.
Factual error: It would not be possible for Kyle to see the woman breast-feeding - and certainly not as shown. Kyle was driving an SUV in the left lane and Swin was the front-seat passenger. When a car was approaching the SUV from the right-hand lane and the rear passenger area was approximately side-by-side at the SUV's passenger window (which is DARK-TINTED!), Swin looked toward the car, but his face was right in front of the frame around the windows - he would, at most, see the woman's left shoulder... and the baby was feeding "on the right." I doubt Kyle would have been able to see any part of the woman when he turned his head to look. At most (and this is unlikely given the height of the SUV), he might have gotten a partial glimpse of the woman's left shoulder and only after the car she was riding in was in front of the SUV's windshield (but still in the right-hand lane).

Factual error: The Mahindra tractor in the film is newer than the 1980's setting. The tractor appears to be a '90's model. Mahindra tractors were not in the American market in the 1980's. Also, the "plow" used in the plowing scene was actually a "middle buster" plow. This plow would not be used at this stage or soil preparation. A turning plow would have been more accurate.
Factual error: The film consistently mistakes Absinthe ban with Thujone ban. The United States Food and Drug Administration (US FDA) lifted the ban on Absinthe in 2007, 13 years before the events of this film. Thujone is still banned, and Absinthe products must contain less than 10 mg/kg Thujone content.
Factual error: Medical doctors in the U.S. do not simultaneously use "Dr" as a prefix and "M.D." as a suffix, but the business card Grace had on her refrigerator for her hepatologist had "Dr. Perkins, MD" on it. The business card should have included his first and last name followed by "MD" (or "M.D."). Dr. Jane Doe, for example, would be used by a person with a Ph.D. (Doctor of Philosophy). The business card also lacked a phone number and office address. (00:06:19)
Factual error: After Maya Peters is brought into the recompression chamber because of an injury, the timer is shown counting down by hundredths of a second and skips from 1 to 0 without showing 0.99-0.01. (01:24:30)
Factual error: Rich told Jamie, "There was a car accident. Guy came in. I cut when I should've stitched or stitched when I should've cut. I don't even know. His family sued in civil court, and I lost everything." A doctor working at a hospital would have been required to carry malpractice insurance, which would have protected him from "losing everything." Also, it would be difficult to prove that a car accident victim who died during surgery was a victim of malpractice; most cases are settled out of court. (00:38:30)
