“ Karnan” is a project titled for a “ Mammootty” movie, a decade back, which was supposed to be directed by Shaji Kailas. Even before completing the pre-production, Shaji Kailas left the project. It is said that due to the budget problem, the film was dropped. Now, it is said that “Madhupal" will helm the project. Shaji said that the screenplay is the best, which he had never crossed in his career. P Sreekumar had put enormous efforts to make the screenplay, the best. Madhupal, who has undertaken the project now, says that there is a lot of research work, needed. He also states that Prithviraj Sukumaran movie, “Karnan” and Mammootty’s Karnan could not be compared. Both of the movies will be seen in different perspectives, says Madhupal.
