Where is Dadaji?

The presence of Dara Singh was sorely missed . I mean, this is a boxing movie which has the deols. And there is no Dara Singh??? Not having the original he-man of the industry is nothing short of sacrilege!

Dara singh could have been Dharmanendra's father and coud have been to this movie what Mr Miyagi was to Karate Kid.

At least they could have hung a portrait of Dara Singh in some of the frames, but it is surprising that they did not even think of that.

Can someone from the industry please shed some light on this notable ommision from an otherwise classic epic? Thank you.
