Mani Ratnam's multi-starrer that he jointly produces with Lyca Productions is gearing up for shooting soon. This as yet untitled AR Rahman musical is said to be a gangster epic with one of the biggest ensemble casting ever. Simbu, Vijay Sethupathi, Fahadh Fazil, Arvind Swamy, Jyothika, Aishwarya Rajesh and many more are associated with this film.

The news is that the director has signed on Aditi Rao Hydari to play a pivotal role in the film and this would be his second film with her following 'Kaatru Veliyidai' (Karthi's 'Cheliyaa' in Telugu) for which her intense acting was well received by both critics and general audiences.

Aditi is currently reveling in the success of 'Padmaavat', in which she has played the role of Mehrunissa, Alauddin Khilji's wife.
