Crew members filming a Bollywood anti-smoking movie will have to cough up a fine if they are caught puffing up on the set, a newspaper reported on Wednesday.

Kumar Mangat, the producer of "No Smoking,'' told the newspaper that he has hired a cameraman to catch offenders in action.

"Many people try to smoke on the sly, so I have told my cameraman to be very alert at all times,'' said Mangat. "Sometimes when caught the offenders protest that 500 rupees is too high an amount,'' the daily quoted Mangat as saying.

However, he insists they pay up and plans to donate 1.12 lakh rupees collected over the past two months to a cancer hospital.

The movie is about a chain smoker, played by Bollywood heartthrob John Abraham, who undergoes rehab to help him stop smoking and save his marriage.

Abraham has quit smoking and has not been caught cheating, he said. Among those recently fined was upcoming actor Ranvir Shorey. "I think this fine is a bit heavy on the pocket, but it's done in good spirit,'' Shorey told the newspaper.

"Anyway I'm trying to quit smoking, so I think this should help.''
