They're both searching for their characters.
I once had a producer tell me that character is "picking your nose with a .38." He meant the pistol, of course, unless he had something else in mind, which I'd rather not know about. But character is not "picking your nose with a .38;" it's not wearing a fedora or a handlebar moustache, driving a tricked out Mini or even carrying a .44 Magnum, "the most powerful handgun in the world". Though many people, like this producer, seem to confuse superficial attributes with character.
Character is the decisions and choices the character makes. But to get to that you have to ask yourself and your character some basic questions. What does your character want and/or need? And why? To what lengths are they willing to go to get it? Will she choose X over Y? What is he willing to sacrifice to get what he wants? Plus other questions such as these and the usual basic backstory questions about everything from their background to their eye color.
Even in Dirty Harry's case the Magnum is only a character attribute or "tic," if you will. But it isn't Harry's character. Harry's character comes out of the choices Harry makes, choices to defy the system, do things his own way and get justice at any cost, not giving a damn about the legal niceties.
But how do you get to know your character? One way is to get to know your character's backstory. And that backstory will guide you to your character's decisions and make him consistent. Actors, like writers, want to know their character's backstory so they can know how and why the character reacts this way or that in a certain situation and thus how to play the part. Writers and actors have a lot in common. The main thing is that they both have to find the heart and soul of their characters.
And even though actors are handed a script most scripts are like a blueprint for a building. The basis for the building is there but right now it's just lines on a piece of paper or a computer screen. In this sense writers and actors have a lot in common and they can learn from one another. Not too long ago I did a
review of "The Right Questions for Actors" by acting coach Jeanne Hartman. In it she asks fifteen questions that actors should ask themselves when considering their character. Some of these can help us writers see our character's secrets, while others will help in seeing the power relationships (who's dominant and submissive) between characters, etc. Most, if not all, of these questions are good things for writers to consider when writing our characters. Spiral bound and with worksheet pages, it's not a bad guide for writers as well as actors. And it might also be good if we put ourselves in the heads of our characters the way an actor might.
The bottom line is that we can both learn from each other's crafts. Even if we're not writing for the visual arts, stage, screen, television, the art of the actor can help us get into the heads of our characters.
