Bollywood's new flying superhero has asked fans, especially children, not to imitate his onscreen death-defying stunts after a man leapt off a cinema balcony in central India, breaking his leg.

"The action scenes are meant to be enjoyed, not imitated. Please do not indulge in these stunts," Hrithik Roshan, who plays "Krrish", a Superman-style hero who saves the world from a mad scientist, wrote in a newspaper on Monday.

Newspapers said at least two people had hurt themselves trying to imitate the stunts from the film that opened last week.

A 24-year-old man was in a hospital with a fractured leg in the central city of Bhopal after he leapt from a cinema balcony and landed on the audience below.

An 11-year-old boy also suffered injuries in a separate accident, newspapers said, but no details were given.

"Those action scenes are dangerous... I did the action scenes with full safety precaution," Roshan said.

"...stop scaring me by trying to do my stunts in Krrish."

The $10 million "Krrish" opened to huge box-office collections, as children and adults made a beeline to watch Bollywood's own superhero leap from tall buildings, beat up the baddies and woo his lady love with song and dance.
