Apparently, during her meeting with Mary, the two discussed certain aspects of the script and found some differences in the real and reel facts.
Apparently, a scene in the film shows the protagonist shaving off her hair in anger to register a protest at some disagreements she'd had with her coach and federation authorities. But, it turns out, Mary told PC that she had actually tonsured her head for new, thicker hair growth.
Consequently, the actress suggested to director Omung Kumar that he make the necessary changes before the film's next schedule in October.
Taking a cue from Milkha Singh, who was actively involved in the scripting of his biopic, PC is keen that Mary is kept in the loop.
