With the much awaited 'Kochadaiyaan' nearing completion, its makers are planning big to promote the movie, especially among the children.

It has always been a formula of Superstar Rajinikanth to satisfy children with his films, for he believes that children can bring elders to cinema halls.

In line with this, caps, t-shirts and key chains with 'Kochadaiyaan' logo and Rajini's picture will be out in the market soon, to attract kids and to create a buzz on the movie.

Also, it is said the costumes Rajini used for the movie would be sold on auction, and the proceedings would go for charity purpose.

Post production works for the movie are currently on and director Soundarya R Ashwin is maintaining details regarding the movie as closely-guarded secret.
