Director Rakesh Roshan Thursday said he was amused by filmmaker Ivan Rana's claim that his film "Krrish" was a lift.

According to Rana, he wrote a story - "Superhero" - in 2003 and showed it to Roshan, who asked him to leave the details with him. Later when Rana contacted him, he alleges Roshan refused to film the story.

However, Rana didn't register the story anywhere. Now he says he is shocked to see the promos of "Krrish", which has the same storyline that he showed Roshan.

"I am laughing at it and don't want to give importance to it," Roshan told on phone from Mumbai Thursday.

A source from the Roshan camp said: "Rana is doing all this for publicity and there is no truth in his claims."

Rana has told reporters: "I had also written about a wire technology from Hong Kong. Even the superhero mask I'd designed has been used."

If he files a case and succeeds in satisfying the court with evidence, the July release of "Krrish" may be stalled.

Last year Nagesh Kukunoor's critically acclaimed film "Iqbal" had also been accused of plagiarism. A Delhi boy had claimed that the film's plot was stolen from a story penned by him.
