The superstar along with Keralite Nayan Tara, a leading Tamil actress, was filming a song sequence for 'Kuselan', which is a remake of Malayalam block-buster 'Katha Parayambol'.
The film is directed by P.Vasu.
The shooting is taking place in the backwaters and two snake-boats have been hired for the song sequence.
A huge security cordon has been thrown around the superstar.
The over-enthusiastic fans of Rajnikant even got onto the boats and reached closer to the star.
The fans shouted slogans for Rajnikant, who emerged on one boat in a spotless sandalwood colour kurta and waved to the crowd of fans.
He will spend the next two days here to complete the shooting of the song sequence.
