Bachchan is reprising his role of ACP Jai Dixit for the third time in the action franchise while Aamir plays the main antagonist. "It's absolutely brilliant to be working with Aamir. You get to learn so much.
He is so much fun on the sets. He is like a child on the set, he is so involved and enthusiastic about everything," Bachchan told PTI.
When asked about his equation with Aamir during the shooting, Bachchan, 37 said, "I think every actor learns from other. As an actor you feed off the energies of each-other. I see my father still learning from a lot more junior actors than him.
So I think as an actor you learn from everybody and you should." Bachchan said it was a challenge to play the same character thrice as he had to add new elements.
"The challenge is how do you repackage that same character and make it as interesting as possible. You can't allow the audiences to say 'Oh we have seen this earlier'."
Bachchan does not find it boring to reprise his character again and again. He said he enjoyed the fun that Jai Dixit and Ali (Uday Chopra) have together in the film. He is reuniting with Abraham for the sequel of 'Dostana' which will have a new leading lady.
