"I have just finished reading 'Conversations With Mani Ratnam' by Baradwaj Rangan. If you enjoy cinema, then you must try and get a copy of the book. A great insight into the mind of someone I consider a cinematic genius," tweeted Abhishek.
Ratnam, 56, is known for his landmark Tamil movies like "Mouna Raagam" (1986), "Nayagan" (1987), "Anjali" (1990) and "Thalapathi" (1991).
Married to actress Suhasini, Ratnam was honoured with the Padma Shri in 2002 and has won several film awards, including six National Awards.
