I had known that I wanted him to be Tamaki, but I still left auditions open anyway to see if I could find any new talent who could have swayed my decision. And well, I didn't, so Lucien got the part anyway.
After that people got mad AT ME for casting Lucien. e.e;
So it turns out asking people to audition always blows up in someone's face, whether it be the producer's or the auditionee's.
THOUGH. I do understand what you're saying, Sukisho. It can be seen as a waste of time, but you kind of can't tell what a producer's motivation/creative license is for that kind of stuff. And if anything, you can not cast that person if they audition for your next project out of spite (:
