Bob was the eighth child in his family, so he was named Krishnamurthy, which also happened to be his uncle’s name. There was a lot of confusion in the house, so they changed his name to Madan.

During the shooting of Mappillai, Bob was injured in an accident. His assistant was also with him. When the car was nearing Vagaikulam, a dog crossed the road. In order to avoid hitting the dog, the driver applied a sudden brake. Because of this, the car capsized. Bob, his assistant, and the driver were seriously injured. However, Bob managed to break the glass door and save the driver and his assistant. The three were taken to a hospital for treatment. After the treatment, Bob participated in the shooting.
