Ripped off from the F.I.S.T.
My dear Fellas!!
This movie is pretty much a rip off of the 1978 movie of Sylvester Stallone name F.I.S.T.
Infact, even the scenes (may of em, including the climax court scene) are almost ditto as of the original one.
The story line is the same aswell!
and yeah i do agree that the movie guru was supposed to be based on the life of Dhirubhai Ambani but maybe Mani Ratnam took the concept and then planned as per his will and the history!
Peace!
