Chennai, Nov 12 (IANS): Superstar Ajith Kumar's latest Tamil outing "Vedalam", which raked in Rs. 15.3 crore on release day in Tamil Nadu, has emerged as the biggest box office opener in the language since last year's blockbuster "Kaththia", according to a trade analyst.

"With Rs. 15.3 crore on the day of its release in Tamil Nadu, 'Vedalam' has become the biggest grosser in Tamil filmdom, surpassing the previous record of Vijay-starrer 'Kaththia', which had grossed Rs. 14.3 crore on the first day," trade analyst Trinath told IANS.

Directed by Siva, "Vedalam", also starring Shruti Haasan, is the story of a don who helps a girl avenge the death of her parents.

Despite receiving mixed reviews from critics and fans alike, the film has managed to impress Ajith's large fan base.

It's critical that "Vedalam" continues its dream run, says Trinath.

"With a phenomenal opening, the film should continue running to packed houses for at least a week for it to enter the profit zone, especially for the distributors. Rains in Tamil Nadu had played spoilsport this week but it hasn't affected the film majorly," he said.
