Don't Say A Word (2001)

Continuity mistake: When Brittany Murphy writes down the number on the glass she writes it backwards because that's how she sees it in her mind. Watch closely, though, and you'll see a perfectly normal 2 which isn't written as a mirror image of 5. Later, when Michael Douglas realizes this catch, he looks at the piece of glass again, this time from the other side, and the 2 has turned into a 5, which apparently was written in a different style.

Nathan Conrad: Does she have a new hiding place that I don't know about?
Aggie Conrad: Probably... she's been running around the house like a wild cat all week.
