Nawazuddin will play a powerful role in the out-and-out commercial extravaganza, said a source.
Nadiadwala is said to have been keen to cast someone with the ability to perform the character dramatically, and Nawazuddin fitted the bill to the T.
This will be the first time Nawazuddin will work with Nadiadwala and Salman.
Earlier, he received a lot of accolades for his performance in "Talaash" and "The Lunchbox".
