Kung-fu star Jackie Chan is determined to keep his movies clean, because he is aware he is a role model for children. Chan insists his martial arts films may be action-packed, but he works hard to keep them free from violence, sex and profanity. He says, "I have a lot of action but no violence. I have a lot of comedy but it's not dirty comedy. I never say (the) 'F' word. "I have to be very careful because I'm a role mode for many young children. I feel that there are a few things in the world without cultural barriers. My movies is one of them."
