So it's obvious that we're just as thrilled about their third film together - yes, the superhero film.
And it just got bigger and better!
We hear, Amitabh Bachchan might be part of the film that also stars Alia Bhatt.
We really hope Big B signs on the dotted line because he and Ranbir have narrowly missed chances of sharing screen space.
The superstar was in consideration to play Ranbir's father in the latters home production Jagga Jasoos. Bachchan was also approached to play Sunil Dutt in the Sanjay Dutt biopic with Ranbir playing Sanjay.
So will they be third time lucky? Here's hoping...
