Southern star Kamal Haasan will unveil a 4 minute promo of his much-anticipated film "Viswaroopam" (Viswaroop in Hindi) on June 30.

The 4 minute 15 second video, which the makers have described as a "stunner", will reportedly feature some footage including some comedy scenes from the film.

The pre-release hype has also raised the film's expectations following the successful screening of the film's first trailer at the recently held 13th International Indian Film Academy (IIFA) awards.

The 1.21 minute trailer received rave reviews worldwide, so much so that Kamal was offered a Hollywood project with one of the most popular producers.

The actor is all set to work with Barrie M. Osborne, the producer of the popular "Lord of the Rings" trilogy. Osborne, who personally congratulated Kamal after watching the trailer, had expressed his interest to work with him.

Osborne and Kamal together announced their tie-up at the IIFA awards and are hoping to produce a film that would envisage an Indian tale in Hollywood style.

While "Viswaroopam" is garnering good response from all quarters, the film has also drawn brickbats from some people. Apparently, Kamal is facing the ire from members of the Hindu Makkal Katchi (Hindu People's Party (HMK)) over the film's title.

HMK party members have criticised the actor for using "Viswaroopam," a Sanskrit name as the film's title. In a letter written to Kamal, HMK head Kannan has stated that the movie's name has to be replaced with a pure Tamil name.

HMK party is widely known for targeting celebrities as well as their films as part of the group's moral policing initiatives. This is not the first time that a Kamal-starrer flick has landed in trouble.

His last release "Manmadan Ambu" was dragged into a controversy by HMK members for using context in a song that they believed hurt Hindu sentiments.

Whether it is for a controversy or for his magnanimous production using latest technology, Kamal's films are always in the limelight. "Viswaroopam" is no different from this.

The film, a spy-thriller, is expected to release in August. Besides playing the leading role, Kamal has also written, co-produced, and directed the movie. The movie is being made in several languages including Tamil, Telugu and Hindi.

Besides Kamal Hassan, the film's star cast also includes actress Pooja Kumar, Andrea Jeremiah, Bollywood actors Rahul Bose, Jaideep Ahlawat, Amrat Chakraborti and Zarina Wahab.
