The very moment director Omung Kumar announced his biopic film on Mary Kom, the news spread like wild fire. After scouting for the right actress, they finally zeroed down on Priyanka Chopra to play the part. Since the major task of finding the heroine had been taken care of, the film's makers are now leaving no stone unturned to make the film look as genuine as possible.

Sameer Johal (who is also the trainer for Farhan Akhtar in the upcoming Bhaag Milkha Bhaag) has already started to train Priyanka for this film. If that wasn't enough, the makers have even got Rob Miller (Chak De! India's sports action director) to train Priyanka in the ring sequences.
