The production house for the untitled film and the actor couldn't agree on his remuneration and commercial terms. It seems that Aamir Khan will have to wait a little longer for a sci-fi adventure. The actor was in advance talks with Excel Entertainment for an upcoming time-travel drama to be directed by debutant Nitya Mehra.

Says a source close to the development, "Aamir had several script narrations with Nitya. He was really impressed with the script. But eventually they couldn't reach a common ground on financial matters. It is an amicable separation between the two."

It has been learnt that the makers are eager to find a replacement and are in talks with other actors for the role, one of them being Hrithik Roshan. As far as the leading lady is concerned, Deepika Padukone was reportedly in talks to star opposite Aamir. But with him out of the project, it remains uncertain if she'll still be a part of the film.

Despite repeated attempts, both Excel and Aamir remained unavailable for comments.
