Where's your $180 million figure coming from? Both The Numbers
and Box Office Mojo
report a production budget of $150 million (and, The Numbers also points out that the DVD sales for the movie were an additional $30 million).
It's in your links.
$187 million is the films overseas gross.
I thought the casting was alright, except for Uncle Iro being so skinny and acting completely different than the Anime character. That, and the butchering of the pronounciations were my biggest complaints.
This and the race bending issue became the least of the films problems upon release IMO.
The acting, the directing, the editing, the pacing, the character development & motivation, the choreography was ALL bad. All of it!!
