Corrected entry: When Anna and Ben are running through the Prague train station in order to catch the train to Berlin, Anna is wearing blue jeans. But when she's actually getting on the train, you can see she's wearing a short black skirt. In the next scene, when they're already on the train, she's wearing jeans again.
Corrected entry: McGruff steals everything out of Ana's purse, leaving only the stickers. Yet, later on she waltzes right across the border into Austria without a passport. And there's no guard at the border station to even question her.
Correction: Realize that both Italy and Austria are in the European Union. Many internal borders are not controlled anymore. I've been able to travel between conuntries without seeing border guards.
Correction: The one in the short black skirt is a secret agent following her.
