Before she was a goofy nerd-turned-princess, Catwoman, or in The Devil Wears Prada, Anne Hathaway was just a girl playing a girl in a commercial, who happened to be in love with her neighbor. The boy reassured her that even though they were selling their house, it would "take time" and that they'd have "the whole summer together." That is, until they realize it's Better Homes And Gardens that's selling their house, and the tears commence.
The YouTube uploader describes it as such:
This is a commercial we did in 1997 and according to her mom on the set, it was the first time she was ever in front of a camera. Only 14 yrs old, there was no doubt from anyone that day that she was going to be a star.
