A silicon gel was needed to add authenticity to the conjoined twins act of Suriya in 'Maattrraan', and a popular Chennai based doctor helped out director K V Anand on this front.

Says the director, "With the help of the doctor, we made the silicon material. We also imported certain thins from Hollywood. The output was awesome."

The much awaited film will hit the screens on Octobe 12. Anand claims it as an action thriller with a difference, while script-writers Subha say 'Maattrraan' carries a message.

The film will hit more than 1,400 screens all over the world, thanks to aggressive distribution strategies of producers AGS Entertainment. It is simultaneously releasing in Telugu as 'Brothers'.
