Rohit Shetty has described Amitabh Bachchan as being like "God".
The director has persuaded the veteran actor to do a dance sequence for Bol Bachchan.
He told the Hindustan Times: "I don't know whether this moment will come in my life again or not. I am working with Mr Bachchan. It's like I am working with God.
"I am still in awe that I am working with him. It is the first time in my career that I have got a photo clicked with any actor deliberately."
The comedy's co-stars are Ajay Devgan and Abhishek Bachchan, who takes on a double role.
Bachchan will reportedly perform the song 'My Name is Antony Gonsalves' from his 1977 film Amar Akbar Anthony.
The 69-year-old actor will make his acting debut in a Hollywood film in Baz Luhrmann's adaptation of The Great Gatsby.
