Ram Gopal Varma explains why he isn’t promoting Abhishek Bachchan’s presence in the Mehbooba song of RGV’s Aag just yet.

He clarifies, “Abhishek is very much a part of the song. I withheld him from the initial promos because it was meant to be a secret. I wanted to reveal his presence gradually. You’ll see him in the song soon enough.”

On another note, Ramu is all set to bring the father-son duo together for the third time in his sci-fi adventure, Time Machine.

This is the same project he had announced with Shah Rukh Khan last year, but later aborted it.

Says Ramu, “Abhishek will now feature in the lead role, and Amitji will be an important part of the action. Nothing about the project has been finalised other than the two Bachchans. I’ll probably make Time Machine next year.”
