Kamal Haasan has issued a warning against unwarranted use of photographs and information concerning the actor without his permission. "Some internet sites are trading information about my released and yet-to-be-released films. T-Shirts printed with my photographs are in the market without getting the required consent from either me or the producer," says Kamal. He said that he will take legal action if necessary against these web sources that have a fan group working behind them. Kamal Haasan, who operates an organised set-up comprising his fans opines that these kinds of activities contradict his principle of not getting involved in politics or marketing. He has also asked his genuine fans to be wary of such clubs that are engaged in commercial exercises and not to offer them support in any form. Kamal Haasan is also in the course of organising legal action against these activities that have been observed in Bangalore and Pondicherry.
