Big starrer films clashing at the box office is bad news for everyone in the industry. 

While the audiences get variety, the filmmakers feel the heat as films when released together eat into each other's business. 

Often it so happens that the stars are affected by this as well. 

But Bollywood's dusky beauty Priyanka Chopra thinks otherwise. 

Her upcoming biopic on 'Mary Kom' will apparently release opposite her ex-boyfriend Shahid Kapoor's next, that is Vishal Bhardwaj's 'Haider'.

However, she is not worried about the clash at all. 

"I'm not aware of the clash since, of late, I've been travelling a lot. Besides, I don't believe in clashes. I'm sure both are great films, from completely different genres. It's been a great opportunity for me to work on the biopic. And I'm sure Vishal sir has also made a superb film," said PC. 

Talking about her experience of working on the biopic, Priyanka confesses that it has been a memorable experience for her. 

"The biggest challenge has been to develop a body that looks like that of a boxer's. It's an athleticyet-masculine look. In our industry, generally, male stars go through physical changes for their roles, while heroines remain the same. But this has been a very different experience," she added.
