Filmmaker Priyadarshan, known for laughter riots like "Hera Pheri" and "Hungama", says he likes the atmosphere on the sets of his movie to be extremely professional.

"If you ever laugh on the set, you will never laugh in the film. When people see me they say I look too serious for a comedy filmmaker," said the 55-year-old, who is now looking forward to the release of yet another comedy "Kamaal Dhamaal Malamaal".

The light-hearted movie features Paresh Rawal and Nana Patekar in key roles.
