The hat
When they first introduce Renee Zellweger's character there is a lot of banter between her and her co-workers about her feathered hat. She even goes so far as to explain it's worth more than their wages. Then she takes the hat off in her bosses office and after being given her assignment, promptly walks out leaving her expensive hat behind. I guess her character, the director and the props department didn't really care about that hat as much as they originally thought they did.
Anyone else catch that?
