Dia Mirza seems to have had a blast while shooting for the movie Acid Factory alongside Fardeen Khan and Irfan Khan. She has nicknamed Fardeen, Kaali Zubaan as whatever evil he spoke came true. In the action movie, Dia being the only female actor had to herself do some of the stunts and being glamorous and at the same time, pulling off these stunts can become quite tough.

While she was doing all these scenes, she was wearing high heels and all the time Fardeen kept on telling her that if she continues she might have an injury and that is what exactly happened when in one of the scenes she sprained her ankle by twisting it. It was not a serious injury though.Guess she must have paid attention to the advice given to her by Fardeen and tried doing the stunts without those high heels on.

She also spoke of Irfan Khan who seems to have impressed her a lot. She says acting opposite him is easy as all you need to do is respond to him. He is an institution of acting and there is so much you can learn from him while you are working with him. They both will pair up again in the movie Alibaug. Irfan for his preparation of the role is on a weight-losing spree as he was requires to shed some kilos from his already sleek frame.

The reason for all this is a sequence in the movie, which sees him in a hospital. Guess there is more to method acting than we thought.
