Director Ajay Kumar is planning to make a biopic on Babasaheb Ambedkar in Tamil. Titled Babasaheb, Raja Ganapathy will play the role of Ambedkar. The film will focus on the lifetime of the social reformer and will not be touching the sensitive caste-based issues. After a gap, ace composer Deva has been roped in for music. We hear that the team is also looking for suitable actors to play the role of other prominent leaders like Bharati and Periyar.
