Kollywood actor Rajanikanth will launch the audio of 'Puli Vesham' according to sources. Rajani was involved in the making of the movie right at a very early stage. It was he who suggested the title of the flick. “Since Rajini sir shares an excellent rapport with Vasu, he came to the discussion one day. At that time, we were in a dilemma to pick a title for the film from the three choices- Mugamoodi, Aarbaattam and Puli Vesham.Because, Rajini sir felt that ‘Mugamoodi’ would not be a right choice since I am an upcoming actor and ‘Aarbaattam’ might not be apt for the script", said RK , the lead actor. The flick is directed by P Vasu and has Sadha as the female lead.
