The person in question is the owner of a floor cleaning product Klinol which was featured in the film and he is suing Metro over the fact that the scene has already resulted in cancellation of orders due to misrepresentation.
The scene in question has Kangana Ranaut attempting suicide by picking up a bottle of KLINOL which has been zoomed in the scene where the bottle, brand klinol & the label is clearly magnified and it has made managing director Kamlesh Khubchandani seething over it.
He says, "I was getting constant calls from friends and relatives and at first I thought it was a mere coincidence. But when I saw the film, I could not believe it.
It is a clear case of maligning my product with the camera zooming onto the label. It is unethical as they didn't take my permission before doing this. I am filing a case against them."
Khubchandani adds that they have raised a question mark over the credibility of my product which has been around since the last 30 years and is a household name. I am afraid that this being a popular film, it might result in jeopordising my sales"
