Gift, The - Another Clothing Mix-Up!
Near the end of the movie when Cate Blanchett walks into her boys' room after they're asleep, she stands in the doorway before walking in. She has on a white cardigan and a blue top undernearth. We see her walk over to her son's bed and sit down on the edge. It's only seconds later, but now she's wearing a white cardigan with a white shirt underneath!
None - you just need to watch the movie!
