The makers of children's comedy "Hari Puttar - A Comedy of Terrors" continue to be in trouble. Though the release date has been fixed at Sep 19, it will depend on the next hearing of the case filed by Hollywood studio Warner Bros alleging infringement of their copyright of the 'Harry Potter' franchise.

Warner Bros filed the copyright case against Mirchi Movies, makers of the film.

Munish Purii, COO, Mirchi Movies, told that the next hearing will be Sep 2 at the Delhi High Court when a judgement is expected.

The last hearing, scheduled at the Bombay High Court on Aug 25, was cancelled.

Asked what action they planned if the judgement went against them, Purii said: "Let's wait and watch. We will see what we can do."

Purii said he is hopeful of a favourable verdict as the title was registered way back in 2005 and feels it has no similarity to the popular "Harry Potter" series.

About the film, Purii said, "It is a 90 minute fun-filled film with four and a half minutes of animation where the two children take the audience for a joy ride."

"It is a film about two children and the power of presence of mind and how the kids create a lot of hilarious sequences," he added.

Music is an integral part of the film and the songs have been composed keeping in mind the situations in the story, he said.

"I think the music will be quite outstanding as we have tried to create fun filled music keeping in mind the storyline."

Besides singers like Sukhwinder Singh, Sunidhi Chauhan, Aadesh Shrivastav, Shaan and Neha Bhasin, new comers like Sameer and Aishwarya of "Sa Re Ga Ma Chote Ustaad" fame have also sung for the movie. The music has been composed by Aadesh Shrivastav and Guru Sharma.

Directed by Rajesh Bajaj and Lucky Kohli, "Hari Puttar" stars Zain Khan, Swini Khara, Jackie Shroff, Saurabh Shukla, Vijay Raaz and Sarika.
