Bachchan, 73, mentioned Ranbir in a tweet while writing about his film Ajooba, which also starred Ranbir's father Rishi Kapoor.
    


    
While Bachchan has worked with Rishi in many films, he and Ranbir have so far shared screen space only in one movie, Bhootnath Returns, where the 33-year-old actor had a cameo.
    


On his own work front, Bachchan is currently shooting for Shoojit Sircar's upcoming thriller Pink, where he is playing the role of a lawyer. The film also stars Taapsee Pannu. We also got hold of a vintage picture of Amitabh Bachchan, during the shoot of Ajooba, with little Ranbir Kapoor and sister Riddhima. Isn't this cute?
