Even before ‘Om Shanti Om' hits the editing table, ShahRukh Khan has agreed to do a sci-fi film with Farah Khan's Shrish Kunder.

That means that all of Bollywood's leading actors Hrithik Roshan, Abhishek Bachchan and now ShahRukh Khan - are at it, trying to produce the best Bollywood superhero.

SRK has also joined band-wagon with this ambitious project. SRK, who has been trying to up the quality of special effects at his VFX studio, will be shouldering the responsibility of the special effects in this film.

On the other hand, Amitabh Bachchan recently lent his voice to the Oscar winning film ‘The March of the Penguins', for the Indian release. Big B admits, "Lending my voice to the film has been a wondrous experience.

I now hear that they want to release the film worldwide and have expressed a desire to go with my voice in the English version."

Against a question he says that, "Yes, the experience of doing voiceovers is wonderful. My first ever film-connected credit title was for the voiceover in Mrinalda's film ‘Bhuvan Shome', the several others followed including one it Satyajit Ray's ‘Shatranj Ke Khiladi'.
