Bollywood actor Irrfan Khan, who got an opportunity to work with Amitabh Bachchan in “Piku,” says they share a "memorable chemistry" in the film and that he'd love to again work with the megastar. "The chemistry between Bachchan sahab and me in the film has been very memorable and I would want to work with him again," Irrfan said. He was all praise of the megastar's performance in the Shoojit Sircar directorial, and added: "In this film, you (audience) will see him in a totally new avatar. The way he has moulded himself in this film, is very endearing and admirable." The film also features Deepika Padukone.
