"Barring production executives and the producer, no one can use a mobile during the time of film shooting. There is no problem in using it during shooting breaks," FEFKA general secretary B Unnikrishnan told reporters. He said the use of mobile phones had become a menace during the shooting.

The decision came after a meeting between the two associations here to discuss means to reduce the cost of film production in face of dwindling profit margins.

"The recommendations that were discussed included limiting the shooting period to a maximum of 45 days per film and an upper limit to the quantity of film roll that can be used," Unnikrishnan said.

He said a 14-member committee, which will also include the actors' group -- the Association of Malayalam Movie Artistes -- will look into all proposals discussed in the meeting.

"A final guideline would be ready after the committee clears the proposals," said Unnikrishnan.

The Malayalam film industry, faced with a series of box-office failures, has been discussing ways and means to bring about financial discipline. More than 30,000 families are dependent on the industry.
