The veteran Indian actor has signed up to star in the big screen adaptation of F. Scott Fitzgerald's classic tale, playing Meyer Wolfsheim - a Jewish man who loves gambling.
Luhrmann has spoken of his joy at Bachchan joining the cast, which includes Leonardo DiCaprio and Carey Mulligan, saying, "(I am) personally thrilled that one of the world's greatest screen legends, Amitabh Bachchan, is joining the cast. Over the years, Amitabh's films have made a tremendous impression on my life and work."
Now Bachchan has revealed he's agreed to shoot his part in the film for free.
Taking to his blog, he writes, "Baz Luhrmann, during his private visit to India last year, had dropped by my office to meet me and presented me with some paintings of a prominent painter that was accompanying him.
"He called last month and wondered if I would do this small role in his film and I agreed. It is a gesture. I have refused any remuneration on this too."
