"Comedy is a serious business and comedy as a genre is quite challenging." This observation was made by Kamal Haasan, who has presented us many rip-roaring films.

Speaking at a special screening of the film 'Kola Kolaya Mundhirikka', for children undergoing treatment for cancer, in Chennai on Friday, he said making comedy movies is not an easy thing.

The veteran, who had acted in comedy films like 'Michael Madhana Kamarajan', 'Kadhala Kadhala', 'Thenali', 'Pammal K Sambandham' and 'Panchathanthiram', said laughter is a best medicine which would help people forget the painful therapies they undergo.

The actor stood in front of cameras for a brief photo session with the children. 'Kola Kolaya Mundhirikka' producers Trisakti Sundarraman and Nalini Sundarraman promised to give the first day collections of film for children with cancer.

The movie's director Madhumitha, screenplay-dialogue writer ‘Crazy' Mohan and actor Karthi Kumar among others took part in the event, which was coordinated by Mahesh Memorial Trust.
