Fun Fact:

The fall was not scripted, Anne actually slipped while filming, although she started laughing they kept with the scene. The director didn’t yell cut because she waved her hand a little (what looked like when she waved at Lily to keep talking) to signal that she wanted to keep filming the shot. The editor eventually chose this shot because he felt it fit Mia’s character a lot more than the scripted shots they had.
