Megastar Mammootty as the epic character Karnan was announced soon after RS Vimal announced about his movie on the same character with Prithviraj in the lead. Mammootty's Karnan is being scripted by P Sreekumar and directed by Madhupal. Few weeks back, there were reports that P Sreekumar is in the final stage of scripting and it will go on the floors in January 2017. But, the recent buzz is that this project might have been dropped. This is because Mammootty hasn't talked about this project anywhere after it was announced. In fact, the megastar has signed a lot of other projects in the mean time. Now, everyone is waiting for an official word from the actor's side.
