Ranbir Kapoor, who will be next seen in Anurag Kashyap's Bombay Velvet, has cautioned his audience that they should not try and emulate what their favourite stars do on screen. A Salman Khan fan recently copied a stunt from the actor's latest release Kick and when Ranbir was asked to give a reaction on it, he said, ''Any form of art makes an impression on viewers but before every film, commercial or TV serial we run a disclaimer that audiences should not try this at home. We have been hearing about such incidents since the time of Superman. Fans used to tie a red cloth as a cape around their necks and jump from their buildings thinking that they too would be able to fly. I don't want to say that we are right and they are not but I just want to make it clear that there are a lots of tricks, harnesses and precautions behind what we do on screen. What you see on screen, don't try that at home.'' Hope our young enthusiasts will take his advice.
