There's one thing you have to remember about Miike as opposed to Kitano, Tsukamoto and many other directors. Miike is just that a director, he's never written or worked on anything that has originated from his own mind, sure he puts his stamp on a film but only as a director. 

As an example, this is a quote from an interview, " I make the movie which is offered to me, with somebody else's money," this is why out of these three directors, I always refer to Miike as a jobbing director knocking them out as quickly and cheaply as possible. 

The source novel for Audition was written by Ryu Murakami perhaps better known to "A" as the writer and director of Tokyo Decadence. Ryu was apparently so pleased with the film adaptation of Audition that he wanted Miike to direct Coin Locker Babies but by the look of it, he won't get the chance to do it.

For a little more insight on Miike here's a link to an interview with him Miike interview with midnighteye.

Cheers Trev.
