6. How do you build character?

Building character is part of the mystery and magic of the creative process. It is an ongoing, never-ending, con­tinuing practice. In order to really solve the problem of character, it's essential to go into your characters and build the foundations and fabric of their lives, then add ingredients that will heighten and expand the portrait of who they are.

four things, four essen­tial qualities that seemed to go into the making of good charac­ters:

Ø  (1), the characters have a strong and defined dramatic need;

Ø   (2), they have an individual point of view;

Ø  (3), they personify an attitude; and

Ø  (4), they go through some kind of change, or transfor^­mation.

The sucess of IRUTHI SUTTU's is characterization of each one the coach, Mathi,etc . The main character Mathi has a defined dramatic need in initial of movie that is earn money for her family then this need transform to a national achiever. Her character has a attitude and point of view about her surrounding,  

The big failure of the good movie THARAI THAPPATAI is the conflict confusing characterization.  

Those four elements, those four qualities, make up good char­acter.  Every main, or major, character has a strong dramatic need. Dramatic need is defined as what your main characters want to win, gain, get, or achieve during the course of your screenplay. The dramatic need is what drives your characters through the story line. It is their purpose, their mission, their motivation, driving them through the narrative action of the story line.

What is your main character's dramatic need? 

The dramatic need is the engine that powers the character through the story line. 

Point of view The second thing that makes good character is point of view. Point of view is defined as the way a person sees, or views, the world. Every person has an individual point of view. Point of view is a belief system, and as we know, what we believe to be true is true. that means that what's inside our head—our thoughts, feelings, emotions, memories—is reflected outside, in our everyday experience. It is our mind, how we see the world, that determines our experience. Point of view shades and colors the way we see the world. that a point of view is acquired through personal experience.  If your character is a parent, she/he could reflect a "parent's" point of view. Or he/she could be a student and view the world from a "student's" point of view. A housewife has a specific point of view. So does a criminal, terrorist, cop, doctor, lawyer, rich man, poor man—all present individual and unique points of view.  Point of view is an individual and independent belief system. Knowing your characters' points of view becomes a good way to generate conflict.

Attitude: The third thing that makes good character is attitude. Attitude is defined as a manner or opinion, and is a way of acting or feeling that reveals a person's personal opinion. An attitude, differentiated from a point of view, is an intellectual decision, so it can, and prob­ably will, be classified by a judgment: right or wrong, good or bad, positive or negative, angry or happy, cynical or naive, superior or inferior, liberal or conservative, optimistic or pessimistic.. Sometimes it's difficult to separate point of view from attitude. 

Transformation: The fourth element that makes up good character is change, or transformation  Transforma­tion, change, seems to be an essential aspect of our humanity, espe­cially at this time in our culture. Change, transformation, is a constant of life, and if you can impel some kind of emotional change within your character, it creates an arc of behavior and adds another dimension to who he/she is.

Character building: 

you're writing a screenplay, the main character must be active; she must cause things to happen, not let things happen to her. It's okay if she reacts to inci­dents or events some of the time, but if she is always reacting, she becomes passive, weak, and that's when the character seems to disappear off the page. like wise  Minor characters appear more interesting than the main character and seem to have more life and flamboyance(very confident in behaviour

A scene like that can illustrate a lot about your character.  Every action, every word of dialogue, every individual character trait expands our knowledge and comprehension of the character.your character occupies the center of a circle and all the other characters he interacts with surround him, then each time a character interacts with the main character, the other characters can reveal, or illuminate, different aspects of the main character. In the same way, different aspects of your main character can be illuminated by what other people say about him or her.

Dialogue

Dialogue is really a function of character. If you know your char­acter, your dialogue may very well flow easily with the unfolding of your story. Writing dialogue is a learning process, an act of coordi­nation..

Dialogue serves two main purposes: Either it moves the story forward, or it reveals information about the main character
