Actor Irrfan Khan says film fraternity needs to stand together against piracy. The 49-year-old 'Piku' star says many other films have been the victim of piracy in the past and source of the leak is probably the same.

"Such cases (online leaks) have happened in past as well. Industry should come together to fight against this. I feel the source of all these leaks is same," Irrfan told reporters. The recent victim of piracy was controversy-laden film "Udta Punjab", which hit the theaters today. The Abhishek Chaubey-directed film was leaked online two days prior to its release.

However, the "Jazbaa" actor says it will hardly effect the business of the movie. "I think the leak will hardly effect 'Udta Punjab' as the hype around the movie is really great," he added.

Irrfan is the newest addition to the array of Bollywood celebrities, who have raised their voice against piracy. Actor Aamir Khan, Karan Johar, Shahid Kapoor, Alia Bhatt and Katrina Kaif have also slammed such actions and have urged fans to watch the film only in theaters.
