Continuity mistake: At the end of the first attack by the destroyer - where she misses the U-boat and throws her bombs further away - the boatswain makes 22, then 23 strokes on the slate of the Control Centre,thus counting the number of depth charges used against the boat. A few seconds later, in a shot from another angle, with the slate in full view, we see only 22 strokes. (01:03:30)
Continuity mistake: When Katya and the Mayor enter his study and sit down, in one shot Katya puts her hand up to under her mouth. In the next closeup it is down. (00:18:50)
Continuity mistake: When Kate breaks her glass, hurting herself, Donald wraps his hanky around her hand, to try and stop the bleeding, but when they start kissing and hugging, there is no blood.
Continuity mistake: In the final scene when the Cajun first shoots Powers Boothe his wound is on his left shoulder. After he stabs the next Cajun between the legs a few seconds later his partner walks over and looks down at him and his wound is now on his right shoulder.
Continuity mistake: Before the start of the match, the teams line up and acknowledges the spectators. In the number 7 shirt for the Allies is John Wark, yet at the start of the second half, the same player is wearing a red track suit and sitting on the reserves bench. At no point was he injured or replaced.
