Bachchan, 71, who worked with Balki in 'Cheeni Kum' and 'Paa', began the filming of his new project in Goa today.
"First day shoot new project R Balki.. Nerves, apprehensions, discomfort, uncertainty, butterflies ! Only redemption, the director!," Bachchan, who won his third national award for 'Paa', posted on twitter.
The yet untitled project will see Bachchan teaming up with Tamil superstar Dhanush and Kamal Haasan's younger daughter Akshara.
The 'Black' star, who arrived Goa this morning, is likely to be seen in a new avatar for the film.
Bachchan's last release 'Bhootnath Returns' is doing good in the box-office.
