Prithviraj’s upcoming movie ‘Karnan’ will go on floors by the end of 2017. This big budget movie will be directed by RS Vimal. The movie was earlier scheduled to start rolling in August. “We are planning to scale it up as an international film and that’s what is taking the time. I can confirm that the movie will begin shooting by the end of this year,” director RS Vimal said in a recent interview clarifying on the delay in the project.
