5 The book is very subtle in narrative. According to MT, he tried to fill in the gaps left by Vyasa. Some of the gaps, like Kunti intentionally letting her 5 sons marry Draupadi is very subtly told by MT. There are many such scenes which require talented actors.
1 Mohanlal: Somewhere along the way he lost the craft of acting. This role, which needs subtlety and controlled acting which was partly seen recently in Pranayam may be lost on this once great actor. He now sleep walks in most of his roles. The Mohanlal of Kireedam and Bharatham is no more.
2 Budget may be too big to recover. Adding Kamal Haasan may help a bit. But MT’s version of alternative history of Mahabaratha may be a bit hard to digest for non Malayalees.
3 Hariharan had his peak with Vadakkan Veeragatha. After that Pazhassiraja failed in script, direction and music. Now to pull off a bigger effort than Pazhassi might be out of his scope. It might be a better idea to get a bunch of directors instead of one.
4 The book, though only a few hundred pages, covers a vast time scale. It will be impossible to cover such a movie in 3 hours.
6 Lack of good women actors. Both Shobana and KPAC are too old for their respective roles and there are not many others who can fill in that shoes.
