What is in Krishnarjuna Yuddham?

The First Look Teaser of Natural Star Nani’s Krishnarjuna Yuddham was released the other day and the response is superb. Nani will be seen in a dual role in the movie as Krishna and Arjun. Many thought that they would fight at some point of time going by the title.
But then the sources say that both of them will come together to fight for one cause and it has to be seen if the reason will be revealed in the theatrical trailer of the film. Krishnarjuna Yuddham is all set for a grand release on 12th April as Summer Release. Anupama Parameswaran is the female lead in this movie directed by Venkatadri Express fame Merlapaka Gandhi.
