Trying to make a character work in a book can be hard. I've found myself throwing out entire days worth of writing in the past because I'd written something with a character or charaters I didn't have a full grasp on. You know, that whole "what is their goal?" thing.
What I find helps me the most is casting my cast. In my head, that is. Generally this is easy, because I watch way too much entertainment and find it easy to put an actor in the part in my head. I can hear their voice, see their mannerisms—all stuff I actually try to leave out of the book because I'd rather the reader fill in a lot of it.
(My goal is to someday eliminate all the "gazing" and "smirks" and other things from dialog attribution... I'd rather the words the characters say tell you what their face looks like. But it's hard, because I also have an inner-Spielberg that wants to make sure the characters do EXACTLY WHAT I SAY.
Stupid characters.
Anyway.)
Which brings me to the leads in BETA TEST. Because the two main characters are not Hollywood household names. They're my friends.
The main character of my book, Sam Terra, got his start in my head because I was picturing my friend Dan. He is a big guy in every sense of the word and not exactly who you picture as the leading man who'll save the day in a big action-adventure (and I'd apologize to Dan for saying that, but he would probably be the first to point it out while at the same time calling me by his favorite nickname for me, "Professor Grandpa," so he can suck it.) That's what I wanted—I wanted to cast against type. At the same time, Sam doesn't have Dan's personality at all. Sam is pretty quiet and reserved. Dan is pretty much the opposite.
I wanted the femme fatale of this book to also not be the usual willy type with perfect boobs and legs up to her neck and perfect in every way for a Maxim shoot. That's now who Sam would fall in love. Instead, he likes Molly, an extremely short chick with blue hair. And I based Molly on Polly, another good friend of mine who might also be my distant cousin, and who happens to be married to Dan.
(I hate to tell Dan but when BETA TEST the movie gets made, I expect the lead role will go to Jorge Garcia from LOST and ALCATRAZ. Sorry, dude.)
You get extra points when you read this book and can tell me what characters I based on Jack Black, a young Steve Buscemi, and Marisa Tomei.
