Rumours are rife that Rana Daggubati has walked out of Vetrimaaran s Vada Chennai, which has Silambarasan aka STR in the lead. It was there that trouble supposedly began. Apparently, though Rana was very impressed by the script when he heard the one liner, he later felt that his role was not as intense as STR s who may walk away with the accolades. In addition, Rana could not give the bulk dates required by the director, who has not been able to confirm when STR is back to start the film.
