All we know is, Trivikram has started his career as writer and then he became writer. He writes the story and dialogues for his films all the time. However this time he's also writing for the promotional interviews of his movies.
From last two days, various promotional interviews of "A..Aa" are going on with Nitin, Samantha, Anupama Parameswaran and other actors taking part in them. Actually they are pre-recorded interviews, that have scripts, questions and answers, provided by Trivikram himself. All these interviews will be shared with web and TV medias soon.
What makes anyone wondering is Trivikram's love to write interviews too.
