Ranbir Kapoor is undoubtedly B-Town hot property. The busy actor is preparing simultaneously for three projects currently- 'Rajnithi', 'Wake Up Sid' and 'Ajab Prem Ki Kahani'.

So much so that he had no time to read Vipul Shah's script which he's penning with his favourite Akshay Kumar in mind.

Sources say that Vipul Shah who wanted to make a fantasy film this time zeroed in on the Hollywood hit 'Action Replay'.

Michael J. Fox played the lead in the original version. The film centers on Marty McFly, a teenager who is unexpectedly sent back and forth in time of present-past-future and meets his parents at his high-school days.

He's sent back in time from 1985 to 1955 and also accidentally attracts his mother's romantic interest. Marty must repair the damage to history by causing his parents to fall in love, while finding a way to return to 1985.

Akshay Kumar dons the lead role while Aishwarya Rai is the female lead opposite him.

Vipul Shah wanted Ranbir in the very important role of Akki-Ash's son. But since Ranbir is so busy with his three projects and another one with Mani Rathnam, he had to turn him down.

If all goes well for the film, this indeed will be a big opportunity lost by Ranbir.
