Background as explained to me by my brother yesterday:
Mia Wasikowka is the woman in the yellow dress. Apparently all she did, for four hours, was run across the street. They built this whole set for her to run across the street. The little tent set up is for Guillermo del Toro, who is in there, but hard to see.
Thus concludes my adventures. I'm very sorry for the squee, but you have to understand that we live in a very small town, and nothing exciting ever happens here. This is the biggest thing I can ever remember happening. It's very cool.
