"Aishwarya was really impressed with the script. She will be seen in a never seen before powerful role. She will essay a Kalari fighter in the film and for the same she will undergo special stunt training," Vasu said in a statement.
Vasu, who has been scripting the film for over two years, says it will be high on visual effects.
"Major visual effects companies are being considered. Animatronics expert from France are being hired for the visual effects in the film, which will be shot in exotic locales of North Indian and some important portions in Cambodia," he added.
The film, to be shot simultaneously in Tamil, Telugu and Hindi, will be produced by K. Ramesh of Global One Studios.
Two top heroes are being considered for the male lead. The names will be announced soon.
Aishwarya was, however, yet to confirm her participation in the Vasu venture.
Vasu, who will also be soon directing the Kannada remake of recent Malayalam blockbuster "Drishyam", has directed over 50 titles in two decades.
He had directed the Hindi film "Hogi Pyaar Ki Jeet".
Meanwhile, Aishwarya, who has starred in southern films such as "Jeans" "Enthiran" and "Raavan", is reportedly also being considered for filmmaker Mani Ratnam's next project.
