Now you know why the title of the film is spelt Maattrraan. It was not numerology but the story of the film that made K V Anand opt for the double letters.
There were rumours that the film was inspired by a Thai film but Anand denies it.
"Just because my film is about conjoined twins doesn't mean that it is inspired by another film. Though rare, 1 in 1,00,000 babies in the world are conjoined twins. So, there are many, many babies and many, many stories to be told.
My story is unique and these two people played by Suriya are also unique. Though joined, they are two different individuals," Anand says.
Pictures were distributed of the twins and also of Suriya alone, so were they finally separated by surgery?
"No, they are not separated. You can say that those pictures are dream sequences!" Anand said from where he was shooting the last song of the film.
"After this song, I will have to concentrate on the post production work which is very important in a film like this. As the audience will see conjoined twins throughout the film, it needs a lot of graphic work."
Kajal Agarwal, Marathi actor Sachin Khedekar and some artistes from Russia play other major roles. The film was shot extensively in Chennai, Bangalore, Hyderabad, Ooty and Latvia. The music is by Harris Jayaraj and story and screenplay by K V Anand and writers Subha.
