The warning 'Smokers Die Younger' doesn't seem to ring a bell with superstar Daniel Radcliffe who has been nicknamed 'Harry Puffer' by his co-stars for puffing about 20 cigarettes a day.
The young wizard rushes to light a stick whenever the director yells "Cut" and has now been advised by one and all on the set of the new Hogwarts movie to kick the butt.
The teenage star finishes around a pack per day and has pals, including fellow Potter star Rupert Grint, pretty worried.
"Daniel has recently been smoking up to 20 cigarettes a day. Every time they call 'Cut', he lights up. It's disgusting. Friends and co-stars including Rupert Grint have been warning him about the dangers of smoking. But he doesn't take any notice," The Sun quoted a source, as saying.
Also worried are the producers of the final flick in the series, who believe that his puffing habits may destroy his schoolboy image. They have now warned him not to be seen smoking in public.
"He's been having late nights out with stars like Kevin Spacey and Stephen Fry and seems to have picked up bad habits from the luvvie set," revealed the source.
In fact, Radcliffe was so nervous doing a stunt himself and turned to his ciggies while his double was absent.
"He was sparking up constantly," said the source.
