The author of the book "Everything you always wanted to know about how to pass a bill" is shown as Tom Altobello, who is the assistant property master for the movie.
When Elle and Grace are talking in front of the coffee stand, the clear plastic spoon Grace uses to stir her coffee becomes a wooden-strip stirrer between shots.
In the hearing for Bruiser's Bill, Elle puts Bruiser in his bag on the table beside her. You can hear her say "my best friend" but as there's a cut to a close-up of Bruiser, you can see Elle's lips in the right hand corner, forming the words "my best friend" silently.
I'm wondering how it is that Elle's hair was glowing hot pink in certain scenes during the movie, and it seemed that she was blonde, with hot pink highlights, which would move around on her head, or glow in the background in the sunlight?
