Continuity: Near the end of the movie when Michael Douglas is about to enter the Customs Office, the insignia on his hat is intact, but when he enters, it has disappeared.

Factual error: In the scene where Melanie Griffith meets Michael Douglas at a Party of the US Army six months after the war began, they are dancing to the song "I'll be Seeing You". This beautiful song was recorded in Feb 17, 1944. It entered the charts two months later, where it stayed for 24 weeks, topping the charts for 4 weeks. They were dancing to a song 2 years before it was recorded.

Continuity: When Melanie Griffith and the children return home from the city (after the bombing) and are greeted outside by Liam Neeson, Melanie has her watch on her right wrist (as she is a lefty). As Liam and the children are heading into the house, you see a close up of Melanie checking the time on her watch and it is on someone's left wrist. When she subsequently goes into the basement to look around, the watch is back on her right wrist again.
