Those working in the film sector have to ensure that things that can pollute minds are not there in cinemas or in the movie industry as this field has the power to affect public thought, Kerala Chief Minister Pinarayi Vijayan said on Saturday.

Vijayan, while speaking at a ceremony to present the Sreekumaran Thampi award to Malayalam superstar Mohanlal, said the film industry should give moral values or lessons back to the public in exchange for the love they show to cinemas and the movie sector.
