Many movie lovers of late 70’s remember the competition between Krishna and NTR on the screen. At one time Krishna seems to be only actor that could beat the records of NTR. They have locked their horns in issues like the making of `Alluri Seetharamaraju’. Now that a biopic is being made by Balakrishna, the role of Krishna would certainly need a mention. And guess what! The producers seem to have approached Mahesh Babu to play the cameo of Krishna. If the sources prove true, Kajal agarwal has also been approached for the role of Jayalalitha. The politician turned actress has done a few movies with NTR.
