Will Mammootty learn Kalari for Mamangam?

The director of Mammootty's upcoming film, Mamangam, has revealed that the actor is the strength behind his project. It was while Mammootty was acting in Bavuttiyude Namathail that the director, Sajeev Pillai, sounded the idea to him. Ever since, Mammootty has been in full support of the film.
Mamangam involves a lot of Kalaripayattu and thus, swordfighting.The characters are all people who lived, and there will be four warriors who are as important as Mammootty's character.
Mammootty had acted in Oru Vadakkan Veeragadha and Pazhassi Raja, and for both, he had practised a bit of Kalaripayattu.
Will the actor brush up his Kalari skills for Mamangam? Let's wait and see.
