I've always wondered why the focus was always on Bollywood when southern cinema constitutes 45 percent share of total revenue of Indian cinema," Pookutty said here.He said that all the major stalwarts from different crafts of cinema came from the south."Take the National Awards for instance. The highest number of awards have gone to artists from southern industry," he said.Talking about the impact of "Baahubali" on Indian cinema, he said: "Today, the character Katappa from the film is more popular than all the three Khans of Bollywood put together."Popular southern stars Shivrajkumar, Shriya Saran and Devi Sri Prasad among others flagged off the two-day event, backed by Fortune Sunflower Oil.IIFA stands for the International Indian Film Academy, which also organises an annual Bollywood extravaganza at a foreign destination every year.
