Generally some directors write the story form the beginning to climax. If important the will picturise the climax in the middle. But Boyapati style is quite opposite. He will give more importance to climax. He will not write climax when he complete the story.
After picturising some portion of the movie he will write the climax. Any movie after completing he will check all the scenes once then according to the output he will write the climax. He is doing this from his first movie.
