Ahahtian a director in his late forties entered films a decade back and struggled as an assistant to various directors. Hailing from an agriculturist family he spent a happy-go-lucky time in college, and when he decided to pack his bags and come to Chennai to try his luck in films as director, he lost his family's support. Struggling with no money he did odd jobs in film companies and became an assistant to anyone who offered him food and shelter.
Anbalaya Prabhakaran, who produces small budgeted films with new directors, gave Ahahtian his first break as a director with Madhumathi, a teenage love story with new faces. The film bombed and Ahatian was back to where he started but again fate had bigger things in store for him. Sivasakti films Pandian, a film distributor turned producer, produced Vanmathi with Ajith and Swathi. The film was a modest hit. Next came Kadhal Kottai from the same banner and Ahahtian became the toast of the industry. Offers poured in for films.
In late 2014, he began work on an untitled project produced by Bharathiraja featuring Santhosh Prathap, Oviya, Vijayalakshmi and Manoj Bharathiraja in the lead roles, but the film was later shelved.National Film Awards1997 – Best Direction – Kadhal Kottai1997 – Best Screenplay – Kadhal Kottai1997 – National Film Award for Best Feature Film in Tamil – Kadhal KottaiFilmfare Awards South1997 – Best Director – Kadhal KottaiTamil Nadu State Film Awards1996 – Best Director – Kadhal Kottai
