Filmmaker S.J. Suryah, who has starred in a few Tamil films over the last few years, says forthcoming thriller "Iraivi" reintroduces him as an actor in a full-length role and he is excited about it.Directed by Karthik Subbaraj, "Iraivi" also stars Vijay Sethupathi, Bobby Simhaa, Kamalinee Mukherjee, Anjali and Karunakaran."I'll be indebted to Karthik all my life. I've always wanted to be an actor but due to the lack of right opportunities, I chose to be a director. Even in the films where I acted, I wasn't taken seriously. 'Iraivi' will reintroduce me as actor," Suryah told IANS.Confident that audiences will relate to the character, Suryah said "Iraivi" will be an important film in his career."It's going to be a very important film in the careers of all the lead actors. When I heard the story, I wasn't sure how the film will turn out to be. But the way it has been come out now, I'm stunned and I'm sure audiences will feel the same too," he said.Suryah, who is currently helming the yet-untitled Telugu remake of Tamil film "Veeram" with Pawan Kalyan, will next be seen as the antagonist in Mahesh Babu's next Telugu outing.
