Vishnu will be opening the year with a bang as the release date of 'Krishnarjuna' has been announced. The film will be released on January 31. The film has Mamata Mohandas playing the female lead and Nagarjuna playing a special role as Lord Krishna. As we had reported earlier, Mohan Babu would be playing a surprise role towards the end of the film. So watch out for the first multi-starrer of the year!
