Continuity mistake: The first time we see John helping Savannah build the new house, he is on the roof and there are 6 rafter trusses installed. About one minute later he is helping put plywood on the wall, and now there are only 3 roof trusses installed. (00:22:30 - 00:23:20)
Continuity mistake: John's staff sergeant military shoulder epaulet markings become upside down in the scene when he and Savannah are having dinner at her house when he comes to see her after his dad died. In a later shot shortly after, they are correct.
Continuity mistake: When Savannah pours the wine during supper the glasses are around 1/4 full and when the angle changes the glasses are about 3/4 full.
Visible crew/equipment: In the scene where John asks Savannah what to do, you can see the mic.
Continuity mistake: When John is repeatedly shot, in one shot there's a bullet hole in his shirt, but in the next shot it isn't there.
Continuity mistake: When John gets shot, his rifle goes from being an M4 into a SAW, then back to an M4. You can see the link dropping from the SAW.
Continuity mistake: In the beach fight, in one shot Amanda Seyfried is far away from John, but in the very next shot she's much closer.
Continuity mistake: During the party at Savannah's parents' house, John is handed a bourbon. Then in the next angle he is handed the bourbon again.
Continuity mistake: In the sex scene, in one shot there's no tear in Amanda Seyfried's eye, but in the very next shot there is.
