Two months ago, Abhishek Bachchan and Shah Rukh Khan announced that they would be collaborating for a film, but not as actors. One would be producing and only the other would be acting. Khan's Red Chillies signed Bachchan for their thriller titled Bob Biswas, touted to be a spin-off on the same character from Sujoy Ghosh's Kahaani.

Ghosh, in fact, is also one of the producers and the film is expected to be on the same lines as the aforementioned mystery. And in case you have forgotten, Bachchan even took to his Instagram to announce the news and couldn't contain his excitement.
