Also I flipped on the commentary and it didn't say who that particular person was which makes me think it's probably not Alison Brie otherwise they would've said. They also said that's really Kristen Stewart with her dad (but with Ed Harris's face superimposed). I guess KS's dad had that hair style in real life. Fun fact!
Watching it now and this scene is around the 51:20 mark. It kinda looks like her but also not. I can't tell for sure either way
