Diamond Ratna Babu is an Indian public relations officer and media consultant who predominantly works in Tamil cinema.
To satisfy his father's wish, he left his bank job, started the "Diamond" film club and screened films for a close group at Devi Bala, Sathyam and Subham theatres in the early 80's.
Tamil films faced some hiccups at the censors, and one such trouble was the reason Babu became a fully fledged PRO, since he realised that being knowledgeable in Hindi, he could be a bridge between the north and the south.
[3] In 1986, when producer Aabhavanan wanted to convert a five-minute documentary into a commercial film, Babu's father canvassed for funds—the concept of crowdfunding is not new – and Babu got drawn into the struggle and was made the PRO.
In 1986, when Oomai Vizhigal faced some hurdle in getting the censorship, Babu was able to liaise with the tribunal in Delhi.
