Now that you have a clear idea of your characters and their roles, you can start writing the dialogue. As a general guideline, the hero's dialogue should demonstrate their personality, motivation, and growth throughout the story. They should have a strong voice, a clear point of view, and a sense of agency. Additionally, they should face challenges, doubts, and dilemmas that test their character and values. For example, in Toy Story, Woody's dialogue reveals his loyalty, leadership, and jealousy as he tries to cope with the arrival of Buzz Lightyear and his own insecurity. On the other hand, the villain's dialogue should show their evilness, intelligence, and threat to the hero. They should have a distinctive voice, a sinister tone, and a hidden agenda. Furthermore, they should reveal their backstory, motives, and flaws that explain their actions and make them more complex. As an example from The Lion King, Scar's dialogue shows his cunning, ambition, and resentment as he plots to overthrow Mufasa and Simba and take over the Pride Lands. Lastly, the sidekick's dialogue should show their loyalty, humor, and personality to the hero. They should have a lively voice, a casual tone, and a fun attitude. They should also add some comic relief or insight to the story while lightening the mood. As an example from Shrek, Donkey's dialogue shows his friendship and optimism to Shrek with his talkativeness and jokes that reveal the truth.
