Amitabh, Abhishek and Aishwarya in RGV's Time Machine

It's a star cast that most filmmakers would dream to work with.

And Ram Gopal Varma has managed the feat not once but twice. Even before Ramu completes the sequel of his film Sarkar, he has already made plans of another film with the Bachchans.

According to a source close to the director, "Ramu has planned to rope in Amitabh, Abhishek and Aishwarya for Time Machine. The director took the decision of reviving the film during the outdoor shoot of his film Sarkar Raj which is currently in progress in Hyderabad."

It maybe recalled here that Ramu had earlier planned to make the same film with Shah Rukh Khan and Kareena.
