"Welcome Back" is a sequel to 2007 movie "Welcome" and there is speculation that Nadiadwala is eager to rope in Amitabh for the role played by Feroz Khan in the original.
Big B, 70, was approached by Nadiadwala earlier as well but could not finalise things for various reasons.
"Firoz Nadiadwala has asked for a meeting and I will meet him next week.
He had earlier met me once and I believe that time I didn't have the time or I didn't like the role. Let's see what happens this time," Big B said here Thursday at the launch of the seventh season of "Kaun Banega Crorepati" (KBC).
Meanwhile, Amitabh has a lot of projects in his kitty besides hosting gameshow KBC.
"Right now, there is 'Kaun Banega Crorepati', then there are films and this fiction TV show, the shoot for that show has also begun. There is Sudhir Mishra's film 'Pehle Aap Janaab.' Then, 'Bhootnath 2' will start in a few months," Big B said.
"Then Balki's film will also be finalised within a week. Sujoy Ghosh's 'Badla', still only a working title, that will start in January. Another project is Rumi Jaffrey's film," he added.
