Bollywood icon Amitabh Bachchan is back in the studios after four months of being away following an abdominal surgery.

If Monday was spent on the sets of Karan Johar's "Kabhi Alvida Na Kehna" in Mumbai, Tuesday was reserved for makeup man Deepak Sawant's Bhojpuri film "Ganga".

"Amitji worked from 11 a.m. to 6 p.m. Monday as he is allowed to work for seven hours. He was comfortable on the sets," Sawant told.

The star plays the role of a Thakur in Sawant's film.

"The first shot is a surya namaskaar where Amit-ji will appear in white dhoti-kurta, moustache and big bindi on his forehead," said Panu Indramohan, who is looking after the publicity of the film.

"Eighty percent of the film is over and we are going to shoot for five-six days with Amit-ji. After that the film is going to be complete," he added.

Up next is Ravi Chopra's "Babul" with Rani Mukerji and John Abraham. Bachchan has also given the green signal to Deepa Mehta's "Komagata Maru" and is in discussions with director Rakeysh Omprakash Mehra for a new project.

According to reports, Bachchan will also make a guest appearance in Gaurang Doshi's science fiction "Happy Birthday" by "Ek Hasina Thi" director Sriram Raghavan.

Clearly, the superstar is already back in the thick of the action.
