Continuity mistake: When Kevin goes to the grocery, he buys Tide detergent. While walking home, the two bags break, but no Tide detergent falls out.
Continuity mistake: When McClane is fighting Col Stuart there is an up close shot where McClane kicks the Colonel and the Colonel grabs his leg. When the camera cuts away he is holding McClane's arm instead of his leg. (01:48:40)
Continuity mistake: Before Edward is looking at the family pictures you can see some scars on his face are open, when the camera focuses back on him the scars are closed.
Suggested correction: Maybe he returned it.
No chance, we see him buy it and then use it in a later scene.
