We have seen heroines making it big in multiple film industries. There are also some heroes who have forayed into other languages and found success. Tollywood is kind of a hub centre for the migrants. Actors from the north as well as the south try a stint in Tollywood.
The most common movement is seen between Kollywood and Tollywood. Kollywood super stars Rajinikanth and Kamal Haasan have repeated their Kollywood success in Tollywood too. Now there are many young actors like Siddharth, Vishal and more recently Suriya and Sathyaraj who have forayed into the Tolly land and are making their presence felt. Call that unity and harmony folks.
