Even though Bollywood is bigger in size, it needs to learn from the Tamil film industry, megastar Amitabh Bachchan said here Thursday.

"Bollywood may be bigger in size and popular, but it still needs to learn from the Tamil film industry. I've shot for a few films in Tamil Nadu, and built strong camaraderie with the industry, and in turn have understood how disciplined they are and the affection with which they treated me," Bachchan said at the closing ceremony of the 10th Chennai International Film Festival (CIFF).

"This is something Bollywood needs to learn from them," said Bachchan, who was the chief guest at the event.

"The Indian film industry may be the largest in the world but a major proportion of it consists of the southern film industry. The Tamil film industry is the pivotal part in the south and one can't ignore it come what may," the actor said.

The CIFF, which began Dec 13, ended Thursday. A total of 154 films from over 50 countries were screened at the festival.
