Plot hole: At the end of the movie we discover that the main character (Claire) was in the plane crash and was sitting next to Eric as the plane started to go down. However at the beginning of the movie( before we are supposed to know Claire was in the crash) Eric can be seen but Claire is not next to him. (00:01:10 - 01:19:20)

Plot hole: Blackbird and Ritchie fake their deaths in order to lure Wayne and Carmen out of hiding. What was the point of pursuing Wayne and Carmen? The only reason they wanted the couple dead was to prevent them from testifying. The problem is .if Blackbird and Ritchie were "dead", the case would be CLOSED. Carmen and Wayne wouldn't be testifying anyway. So why go to the trouble of killing them? It makes no sense.
Audio problem: The day after Operation Mardonius, when the first set of bombs explodes you first see the explosion and then hear it after a second, then as the last bombs explode you both see and hear the sound at the same time.
Revealing mistake: The raid took place at Xmas in 1951. In homage to this fact, the characters wear big coats and one of them even rubs his hands together and goes "Brrr." Yet the movie was filmed in the height of summer. Trees in the background of scenes in London are full of leaves, we never see any mist in exhaled breath and the lighting levels and shadows indicate a high, bright sun.
Factual error: When the captain is arguing with the Armed Services Committee chairman, Homeland Security is mentioned. However this movie takes place prior to Desert Shield, and the Department of Homeland Security wasn't created until over a decade later.

Continuity mistake: When Ronald's girlfriend gets up at the breakfast table, and tousles his hair, Ronald is holding a glass of milk in his right hand. There's a cut to a wide shot, and Ronald is not holding the milk. There's not enough time for him to have put it down.

Other mistake: By the moment that Lea discovers and reads the letter, this, with such typewriting, cannot be written by a six year old boy.

Continuity mistake: Mike Manador watches his girlfriend Gina drive away in a taxi. Behind him a truck can be seen coming down the street. Mike then steps out into street seconds later, but the truck has vanished. Next shot looks up the street and sure there is the taxi but no other vehicles, and you can see the entire street. (01:41:25)
Continuity mistake: During the scene that Bo and Sam kiss, his hair changes between shots. From the back, his hair is completely pulled back. From the front, his bangs are down. (01:27:20)
