The film has Dhanush and Shruti Hassan in the lead. 3 is an emotional love story that boasts to be different and catchy and also means something poetic. Aishwarya Dhanush said, ‘’ I was trying to get something different, at the same time catchy. Nothing too long. And 3 was just perfect for the story too,” she said.
Aishwarya Dhanush further said, “The character of Dhanush fits him perfectly. As Dhanush’s wife I know what all he can do, I understand him well. For this script it’s very important that the hero understands the emotional make up of his character. As Dhanush is aware of what I need, it’s easier for me,” she added.
