Suriya can be the best elder brother for the season now. He has been scrupulously shaping up his brother Karthi's career. Right from his debut film 'Paruthiveeran', Suriya has been taking intense care over reading the scripts page by page. The result? Karthi has achieved in 4 films that was achieved by his brother Suriya in 25 films. 'Thanks to my dear brother' says Karthi as he cannot stop singing praises. But it's Suriya showering heavy downpour of praises for Karthi for his outstanding work of double-acts in 'Siruthai'. Says Suriya: 'Pithamagan and Kaakha Kaakha are the most important films in my career. But it was a backbreaking job for me to carry on with two contrastive characters as a cop and a fraud on street side. But I am enthralled to see Karthi performing both roles in the same film 'Siruthai' that too so early in his career. I have become the publicity officer of 'Siruthai' now and I will publicize the film to a greater magnitude.'
