Just when we thought Shankar's Robot was all set to go on floors came a bad news that Ash might eventually pull out of the ambitious project given the director's plans to shoot the film over a period of two years.

That apparently is not acceptable to Ash who cannot afford to give so much of time to a project.

There are also news doing rounds about Deepika Padukone's inclusion into this sci-fi Rajni starrer.

Shankar and Rajnikant are very fond of Ash, who made her acting debut in Shankar’s film ‘Jeans’. Since then, the director has approached Ash for every single film he has made except ‘Boys’, but every time Ash has turned him down for one reason or another.

It remains to be seen if she has turned him down again for ‘Robot’.

We hear, the actress has already asked Rohan Sippy to start his film Happy Birthday which stars John Abraham besides her due to delays in Robot.

However some insiders maintain that Robot is getting delayed due to security reasons and not Aishwarya refusal.

The major hurdle in rolling the project, which will be shot at different locales in India and overseas, is that the areas have to be scanned from the security point of view. Both Rajnikanth and Ash come under a high protection security network.

Post wedding, Ash’s security has beenoverhauled. All her shoot locales are now thoroughly scanned by the producers and rest of the crew.

Reportedly, Aishwarya was promised Rs 4 crore for Robot which is slated to be a bilingual venture - both in Hindi and Tamil.
