Vanisri has starred in super hits such as Krishnaveni, Prem Nagar, Dussehra Bullodu, Aradhana, Jeevitha Chakram, Rangula Ratnam, Sri Krishna Tulabharam, Bhakta Kannappa, Bobbili Raja, etc. If there was a star heroine in the Telugu film industry, who ruled on par with the heroes, it must be only Vanisri.
