Shooting for the Dhanush starrer Polladhavan is under progress and we have some interesting information about this movie for our readers. Many of you might be knowing that the movie is being directed by debutant Vetrimaaran, well what most of you might not know is that he has apprenticed under Balu Mahendra and Kadhir; so its quite natural that big things are expected of him. But Polladhavan was not the movie that Vetrimaaran intended to make his debut with. He had planned a movie titled Desiya Nedunchaalai (National Highway), but due to various reasons the project never took off and he moved on to Polladhavan.
