Other mistake: While flying home from overseas, Kate is wearing earrings while she is wearing the Army Combat Uniform (ACU). At the time the movie took place, female soldiers were not authorized to wear earrings while wearing combat uniforms. I could dismiss this as a character mistake if Kate was a private fresh out of basic (I once corrected a real female soldier who just finished basic that was wearing earrings), but Julia Roberts is portraying a captain in the movie and a captain would have known better.
Continuity mistake: In the scene where Emma Roberts is talking to the grandparents at the table, the camera shows her phone on the table. But a couple minutes later she gets a call and she pulls her phone out of her pocket.
Male Anchor: There you have it, folks. Young love. Full of promise, full of hope, ignorant of reality.
