New Delhi, Oct 4 (IANS): It's a small film made with a lot of heart. Vishal Bhardwaj's "Haider", his twist on William Shakespeare's tragic play "Hamlet", is climbing up the Bollywood box office ladder thanks to a positive word of mouth, say experts. It has earned a cumulative of Rs.13.07 crore within two days of its release.

The Shahid Kapoor, Shraddha Kapoor, Tabu and Kay Kay Menon starrer hit the screens Thursday along with the big budget entertainer "Bang Bang".

On its opening day, "Haider" minted Rs.6.14 crore, and on the following day, it managed a business of Rs.6.93 crore, registering a 14 percent jump in its collections, said a source from the production team, UTV Motion Pictures.

"The film witnessed a huge jump in most of the regions, including Gujarat, Punjab, Rajasthan," the source added.

Made at a budget of Rs.24 crore, the canvas of "Haider" is dark and violent, but beautiful in its own way.

Set against the unrest in the Kashmir Valley, the story revolves around a man who wants to avenge his father's death. And Bhardwaj, known for giving Bollywood buffs a different cinematic sensibility with movies like "Maqbool", "Omkara" and "Kaminey", has used apt locations and setting to suit the grim and gritty mood of his latest offering.

Industry experts believe "Haider" is performing well, and its collections are poised to grow over the days.

"It has performed really well. The film did pretty well on the first day and I believe it has only become better. The liking for the film is not only limited to single screens as the film is getting a good response from multiplex audience as well. The response for the film at our cinema chain is really good," Deepak Sharma, chief operating officer, PVR Pictures, told IANS.

Sharma said the audience is aware that it's a "very different movie", and its performances and cinematography are turning out to be crowd pullers.

"Word of mouth publicity is working for the film. I would say that the audience is not only appreciating the film because of the publicity, but due to genuine liking towards the movie," he added.

Agrees Rajesh Thadani of Multimedia Combines.

"'Haider' has collected over Rs.11 crore so far and it will grow through word of mouth," Thadani said, adding that the fact that "Bang Bang" released on the same day, has affected the collections that "Haider" could have managed.

"Bang Bang", starring Hrithik Roshan and Katrina Kaif, and directed by Siddharth Anand, is the official Bollywood remake of Hollywood film "Knight and Day". Its exotic locations, high octane action sequences and star power added an additional buzz much before the movie hit as many as over 4500 screens worldwide.

"Haider" is said to have released in around 1500 screens.

Sanjay Ghai of Mukta Arts says "'Haider' is doing decent business. The screens have been divided between both the films, but both the films are little long...If the films had medium or short length, they would have got more screens."
