Omung Kumar said: "This is my debut film, and as a director, this film should work commercially as well. Had I cast any newcomer for this film, people would have ignored the posters.
"Now people are talking about the poster and the trailer, which means people are liking it and it's all thanks to Priyanka. Priyanka will add commercial value to 'Mary Kom'."
While there were also reports that the director and the film's co-producer Sanjay Leela Bhansali are not on talking terms because of creative differences, Omung said: "These are all rumours there is absolutely no issue between both of us."
