Oscar nominee for Rachel McAdams

This^^^^^^!!!!

Yeah. I was really, really impressed with her. Out of the main cast, she was the only one who seemed to realize that an almost completely non-verbal acting style was called for.

Seriously? Olga Kurylenko outshone her easily in this film!

I thought she was very weak -- she seemed unable to keep from getting a smirky smile in scenes where I just got a feeling it wasn't really supposed to be a smily smirky moment. This seems to be a tendency of hers in other movies too.
