Amitabh Bachchan, who had been unwell over the weekend, is on the road to recovery. He has resumed shooting for Kaun Banega Crorepati at Film City. Unit sources say Big B is fine and shows no signs of ill-health. This season's fourth crorepati is jail superintendent Ajeet Kumar Singh from Bihar. The former employee of the Indian Railways says being a voracious reader helped him crack the questions.

Happy space
