(at around 44 mins and 1h 7 mins) The same footage of Paul getting up off the couch and saying goodnight while Meryl lays on the couch is repeated.
In the first part of the movie with day time scenes of Manhattan, the Twin Towers are gone. They return in the nighttime scenes at the end of the movie.
When the Morgans fly out of New York City, it is bright daylight. However, when they arrive in Wyoming, it seems to be twilight. Unless the jet is very slow or they had a layover, this is impossible. New York City is in the Eastern time zone and Wyoming is in the Mountain time zone. Therefore, they would have gained 2 hours when flying west. It should have still been bright daylight.
The couch where Meryl sleeps has a table behind it that initially has a lamp on it. Throughout the movie, the lamp disappears when it would block parts of a shot, then reappears shortly thereafter.
When Meryl leaves Paul early and he keeps on running, she heads back to the farm. While running, she wears tight-fitting gray leggings, but when she shows up in the barn, she has on loose-fitting sweatpants.
None of the characters wears hearing protection when shooting. In real life, no one would forget this important safety gear.
When Emma is chopping wood all the blocks are clearly pre-split.
The Big Dipper in the Wyoming sky is upside down and drawn wrong. The Big Dipper can be used as a pointer to the North Star by using the two outside edge stars of the cup. Extending a line beginning at the lower star through the upper star leads to the North Star. Doing that on the movie's Big Dipper puts the North Star below the horizon, whereas it should be above the Big Dipper.
An experienced shooter like Emma would never allow a first-timer like Meryl to hold and fire a rifle as depicted in this film. By pressing her cheek against the side of the rifle while failing to secure the stock firmly with her shoulder, Meryl would likely have seriously injured herself as a result of the recoil produced by firing. This was demonstrated in the same scene when Paul injured his shoulder despite holding the rifle more correctly.
On the flight from New York City, Paul Morgan's seat belt is extremely loose right before he remove this seat belt upon arriving.
When they are training using a rifle, when Emma first shoots the can, she has the rifle stock at her right shoulder but aims with her left eye. Any experienced shooter would not aim that way.
