We hear that the unit is canning scenes relating to Ramanujan's childhood and his early days in the town, andSuhasini Mani Ratnam,, who plays the ace mathematician's mother, has already begun shooting for her portions.

A source reveals, "This is likely to be a 20-day schedule, and the team will be shooting at locations where Ramanujan spent his childhood. Recently, a song sequence involving Suhasini and the young Ramanujan was shot inside a famous temple there. She was seen decked in traditional attire and looked her part. This schedule is likely to continue for a few more days."

The Tamil-English bilingual has Abhay, grandson of Kadhal Mannan Gemini Ganesan, playing Ramanujan, with Bhamaa as his wife. The film will chronicle Ramanujan's life — right from his childhood to the time he proved his mettle as a mathematical whiz, and his contribution to the world of numbers.
