Actors Vishal and Karthi have been the most profound friends over the years and they havbe been significantly sharing a very good bonding without any problems. Now that their friendship has been extending well into the welfare activities including the development of Nadigar Sangam, they together have good news to share with us all. This is all about an upcoming Tamil film ‘Karuppu Raja Vellai Raja’, which will feature both Karthi and Vishal in lead roles. The film will be directed by none other than Prabhu Deva and this marks his comeback in Kollywood as filmmaker, which happened nearly before a long time with ‘Villu’ that starred Vijay and Nayantara in lead roles. The film’s shoot will be beginning by next year probably after both the actors complete their current projects. Right now, Karthi is busy promoting his upcoming film ‘Kaashmora’ scheduled for Diwali release and is on the final leg shooting of Maniratnam’s Kaatru Veliyidai followed by an untitled film with Vinoth of Sathuranga Vettai fame. Vishal with his upcoming films include ‘Kaththi Sandai’, ‘Thupparivalan’ and newly launched ‘Irumbu Thirai’.
