Was Christine Autistic?
She was certainly bi-polar, but I also got the sense that she was on the autism spectrum. It could have just been the way Rebecca Hall chose to play her, but she certainly exhibited a lot of the traits of high-functioning autistics.
Another phenomenal performance by Hall. At this point, I'm convinced she could make any role interesting--woman sleeping on bus, receptionist eating a sandwich, bored dental hygienist, etc.
