Megastar Amitabh Bachchan is biting his nails because of tension as he gets back to film shooting after wrapping up TV game show "Kaun Banega Crorepati" (KBC).

He shared his anxiety through a tweet that he posted Sunday.

"To bed today. Tomorrow (Monday) 'Bhootnath Returns'. 'KBC' over, film tension starts. May professionalism always bring that in us," he wrote.

The seventh season of KBC will end in December first week.
