Megastar Amitabh Bachchan, who has started shooting for the untitled film directed by R. Balakrishnan, is nervous about it.

`First day shoot new project R Balki...nerves, apprehensions, discomfort, uncertainty, butterflies! Only redemption, the director,` Amitabh posted on Twitter Sunday.

The film, which also features `Raanjhanaa` star Dhanush and actor Kamal Haasan's younger daughter Akshara, is currently being shot in Goa and the 71-year-old is getting nostalgic too.

`It is hard to forget the various films that were shot here, in what circumstances they were made and what they look like now. But each and everyone of those incidents etched a mark on my system."

`The statue of a Portuguese celebrity, where during the shoot for 'Saat Hindustani', in the centre of the street, we had gathered to perform the raising of the Indian flag, as a protest against a rule that had robbed us of our independence,` he posted on his blog srbachchan.tumblr.com.


`Then the various locations on the schedule under production, which have remained close and very close to us and to those that spent time with us. Locations such as the climax of 'Kabhi Kabhie', the boat and song sequences of 'The Great Gambler' and the ride along the river Mandovi, passing by the hospital, now a Bal Bhavan, where Amjad Khan fought for his post accident treatment. And just so many moments,` he added.

Amitabh and Balakrishnan, popularly called R. Balki, had also worked together in films like `Cheeni Kum` and `Paa`.
