The actor was recently forced to have surgery for an internal injury which related to his near-death incident on the set of Coolie 30 years ago.
Bachchan told followers on Twitter: "So back in front of the cameras for the promo shoot of IPL a bit strange, but never too strange ... a spring in the step and mind
"Familiar surroundings, vanity van, ever faithful [director] Deepak [Sawant], my make up, lights, cameras, busy assistants, hushed silences and 'action'."
He will be hosting the opening show of the Indian Premier League cricket series, with appearances from Kareena Kapoor, Salman Khan and Priyanka Chopra.
The 69-year-old Bollywood legend described his body as a "war zone" after being admitted to hospital for abdominal surgery last month.
Bachchan has previously admitted that he was nervous before the shoot of Baz Luhrmann's adaptation of The Great Gatsby.
