Bachchan, 71, said he sometime feels that the choreographers forget his age and still gives him tough moves.
"'Grooving and shakin' with the young at the shoot for 'Bhoothnath Returns'.. At times the choreographer and the production forget how old I am to be still doing this stuff... But to be honest I did enjoy myself, despite the buckets of perspiration after each approaching summer heat filled shot," Bachchan posted on his blog alongwith few pictures.
"And then of course the no regrets of not being able to gym, since, the workout during the song was enough to keep me going for a decade!," he added.
Bachchan had earlier mentioned that he shot a dance sequence choreographed by Ganesh Acharya last month.
'Bhootnath Returns' is a sequel to the 2008 horror-comedy film 'Bhootnath', which also starred Juhi Chawla and Shah Rukh Khan besides Bachchan as the friendly ghost.
