Kollywood actor Silambarasan seems to be unrelenting in his attempts to rope in an ace Bollywood actress for his dream flick 'Vaaliban'.The actor had earlier approached Sonam Kapoor with the project. But she said a clear No right away. The actor however did not abandon his attempts and was attempting to influence Sonam through close sources. The recent buzz is that STR will soon launch the shooting of Vaaliban and that Sonam Kapoor will grace the female lead  as he wished. However, there have been no official reports on the same. The photo shoot of the flick will soon kick start in London. The flick will have Yuvan Shankar Raja scoring the music and Anthony editing it. Seems like STR is to lucky to have approached Sonam at the right time, especially when she was desperately looking for a good break after the major disappointment from 'Aisha'.
