That Ayan Mukerji has roped in Ranbir Kapoor and Alia Bhatt for his next directorial venture is known to all. The untitled project is a superhero flick and for the very first time Jr Kapoor will be seen opposite the “Highway” actress on the big screen. While we can’t wait to see this fresh pairing, it is heared that the “Wake Up Sid” director is now planning to bring Amitabh Bachchan on board for the same film. Well, if that happens then Ayan will pull off another casting coup for sure. Apparently, Ranbir’s best buddy-cum-filmmaker wants to cast Big B in an important role. Let’s hope things do fall into place because it would be interesting to see three very talented actors come together for a film that too for the first time.
