Excel Entertainment's time-travel drama will have to wait for now, or until the time it finds its lead actor.

Yes, after Aamir Khan walked out of Ritieish Sidhwani's upcoming project, owing to a fallout over remuneration and promotion, even Hrithik Roshan has now decided to bow out of the venture.

Buzz is that Hrithik has been roped in to do Ashutosh Gowariker's period epic, 'Mohenjo-Daro' and won;t be able to commit to Sidhwani's flick owing to date issues.

Now the hunt is on for another A-lister to feature in the movie. Grapevine tells that Ranbir Kapoor is being considered for the role. But whether the young Kapoor less will agree to do it remains to be seen.

To be helmed by Nitya Mehra, the production house plans to put the sci-fi flick on floors by early next year.

Despite repeated attempts, Excel Entertainment's head honcho, Ritesh Sidhwani refused to comment on the venture.
