The Bbuddah Hoga Tera Baap star has been reported to be playing Tagore in a Bengali film called The Sound of Silence, based on the poet's life, according to NDTV.
Bachchan said: "I have been reading in newspapers that somebody has made a formal proposal [to play Tagore]. I have been getting some messages from other people. I would be very honoured to portray the role. But no formal proposal has been made 'til now."
Bachchan and filmmaker Prakash Jha have been promoting their forthcoming movie Aarakshan, a socio-political drama which deals with the policy of caste-based reservations in government jobs and educational institutions.
The controversial project was recently passed without any changes by India's Central Board of Film Certification.
