The dream project of director Shankar featuring Rajinikanth has met with a stumbling block its heroine Aishwarya Rai said to be keen in having a baby before she turns 35 (on November 1, 2008). It is strongly rumoured that the Bachchan bahu, who was offered a whooping amount of Rs. 6 crore to act in 'Robot', has conveyed the 'Robot' team about her “inability” to act in the film.

The news, if confirmed would be a major setback for the team, which was gearing up for the shooting to be commenced by June this year. Shankar and co are now in a fix as they face the tough task of finding a replacement to the most sought after girl in Indian film industry.

It is not the first time the pairing of Rajini and Ash is jinxed. She has been in the reckoning for Rajini’s movie since the time of 'Padayappa'. It may be recalled that Simran too withdrew from 'Chandramukhi' stating the same reason, i.e., to have a child.

As things stand now, 'Robot' unit is in the hunt for a new actress, who could fit the role.
