Sports drama "Million Dollar Baby" was the story of a waitress' determination to become a boxing champ and Swank played the protagonist in the film, which did so well that it took home four golden statuettes.
"'Mary Kom' is a very special film and no one other than Priyanka could have pulled off the role," Bhansali told reporters at the trailer launch of "Mary Kom".
"Priyanka is an atom bomb and power packed talent. Her dedication, passion, and commitment toward her work is commendable. If Hollywood has Hillary Swank, we have Priyanka Chopra."
Bhansali also compared Priyanka's talent with Nutan and Waheeda Rehman saying she is in the "same league".
Bhansali feels "Mary Kom" was destined to happen.
"If a film has to happen, it will happen. For this film, we had no meetings or readings. Omung was in the lift and told me he wants to make a film on Mary Kom and I said yes then and there. So, I feel the film was meant to happen," he said.
Directed by Omung Kumar and co-produced by Viacom18 Motion Pictures and Sanjay Leela Bhansali Productions, the movie will release Sep 5.
