Dana Veera Sura Karna is not special only in Tollywood. We can say it is special in India itself because of the following reasons and the records it created.
1) NTR requested ANR to act either as Krishna or Arjuna in Daana Veera Sura Karna. ANR realized from his previous experiences that he will not be a match to NTR when it comes to portraying mythological roles and politely refused it…
reviewers during that time commented that they should have named the movie as “Athratha maharana Suyodana[అథిరథ మహారథ దుర్యొధన ]” rather than as Daana Veera Soora Karna. NTR has immense respect for Duryodhana and insisted that the film shooting unit members should call Duryodana as “Suyodhana” only which is his original name.
5) This is the 2nd movie in which NTR acted as Duryodhana. The 1st one is Sri Krishna Pandaveeyam which was released in 1965. This is the second movie in which NTR acted as Karna as well. In the 1st movie, he acted as Karna in a small drama which is played in the movie
