First of all, you might wonder why the gent on the left is wearing sunglasses while he fights the ancient Mahabharata war. Well, because he is M. Karunanidhi, of course. He and his late arch-rival, MGR, who was buried in his sunglasses, never look directly on the light of sun or moon.
Even more interesting is the fact that the Dravidian movement, of which Karunanidhi is one of the senior members, was originally firmly anti-religious. It has had to move gradually in the direction of religion -- since that's what people want -- but showing Karunanidhi's son Stalin (named after Joseph Stalin, naturally) as the god Krishna is really something.
