Sangram, 30, was approached to play the role of Rustam-e-Hind,in a Punjabi film, which he even agreed to do. But, apparently things did not work out.
"I was going to do a biopic on Dara Singh, talks were on. But due to right (copyright) issues with his son, things didn't work out," Sangram told PTI.
When contacted, Dara Singh's son Vindoo, remained unavailable for comment.
Sangram, who has appeared in several reality shows, revealed that he is currently working on another biopic on a noted wrestler but was not keen on disclosing the name.
