Acoording to latest buzz, after his blockbuster Sivaji, Shankar has approached SRK for his next venture, supposedly, a sci-fi flick.

A source close to the director says, "Shankar wanted Hrithik but it seems that he won't be able to do the film because he has already committed to his father Rakesh Roshan for Krrish 2.

Now, Shankar has approached SRK and he has agreed."

It was only on the actor's request that the shooting will commence after a while. SRK has agreed to begin shooting for Shankar's film only after as he completes Shirish Kunder's film, which is untitled so far.
