Nitish Bharadwaj has revealed that he had initially refused to even give a screen test for Lord Krishna's role in producer BR Chopra's TV show 'Mahabharat' because he felt he couldn't do it. "I told [Chopra], 'You need a more experienced person'," Nitish said. "He [replied], 'You always wanted...a good role, at least appear for the screen test'," Nitish added.
