Yes it was only Vishnuvardhan who could surive the turbulance in kannada filmdom.Both Rajani and Vishnu who are best firends complimented each other in Mid 70 s and climbed the ladder in their fields.Rajani played roles in Vishuvardhan kannada movies and later Visnhu acted in tamil movies with the help of Rajanikanth when he faced some trouble in early 80 s. But the truth is that Vishnuvardhan who is about to complete 200 movies in Kannada,still cant support Rajani publicaly,because immiedietly some outfits will call Vishnu as anti kannadiga and will create trouble. so we can only blame the system
