The trailer and music of Mani Ratnam's most anticipated film 'Ponniyin Selvan Part 1' was launched amid much fanfare in Chennai on Tuesday. Apart from the director, the event was also attended by stalwarts like Rajinikanth, Kamal Haasan, and Shankar who were completely awestruck with the way film was made. Shankar even called Mani Ratnam the ‘first pan-India director’.
