Hrithik will face another challenge in Rakesh Roshan's next

The father-and-son duo of Rakesh Roshan and Hrithik Roshan has had a fantastic record so far. All the three films that they have worked together so far - Kaho Naa Pyaar Hai, Koi Mil Gaya and Krrish - have created box-office records. Now that the father-son duo is all set to come back together for Krrish 2, they want to leave no stone unturned to prove that their combination is unbeatable.

It has been learnt that although Rakesh Roshan has been ready with the first draft of Krrish 2 for some time now, son Hrithik Roshan is not very happy with the crucial climax sequence. Rakesh Roshan is known to pen his own script and the duo has major differences over the climax of the film.

Our sources say that although the father and son have finalised an idea to work on the film where Hrithik will face another powerful villain who also has special powers, they have not been able to finalise how to go about the story. Rakesh Roshan has already written the first draft of the film without dialogues but son Hrithik is far from happy with it. He has his own point of view over the climax. Earlier the Roshans had decided that Hrithik himself will play the villain in the film but that would mean that there would be three Hrithiks in the film in the form of Rohit from Koi Mil Gaya, Krishna from Krrish and now the villain in Krrish. That's when they decided to cast Shah Rukh Khan in the film who did not agree to do the film. Now they are hunting for another actor for the same role.”

Our sources further add, “There are also talks with Rakyesh Mehra to direct the film and Rakesh Roshan will only be the writer of the film. However, that is yet to be finalised and will only be decided once Mehra takes time off from his film, Dilli 6.”

Rakesh Roshan and Hrithik Roshan remained unavailable for comment. When contacted Sunaina Roshan didn't categorically deny the improvisations being made in Krrish 2 script. She says, “As far as I know, we are currently concentrating on Hrithik's film, which will be directed by Anurag Basu. We will start working on the final script of Krrish 2 some time in the middle of this year.”
