This may not be the place for this. If not, please let me know and I'll remove it at once. But if you like it then also, please let me know.
Wendy posted very recently about her characters not doing as she wants, which is often the characters wont. Characters are like children, and - strangely enough - exactly like the actors who will perhaps portray them at some future moment, usually when you are dead and your estate sells your back catalogue cheap coz they have no idea what REAL art is worth.
Having had a little to do with serious thespians, I find that like some characters, they are spoilt, lazy, ornery and at times idiotic. Treat them as equals. threaten the crap out of them. Bring in new characters who will work harder and cheaper and do what they're told (at least until they get known and become just like those they replace).
But on the subject of characters (and not multiple personalities), I offer this little piece I wrote a while back about characters. Please enjoy (I did say please :) )
