Emraan Khan and Irrfan Khan working together in Mahesh Bhatt's 'Killer'. Director Raksha Mistry laughs, "Emraan and Irrfan are just fabulous and their characters are like Tom & Jerry. They have a lot in common. I think they should be married." And also adds, "It definitely helped that they had worked together earlier and since they are playing themselves in the film it didn't really require them to work too much on their roles. They were more comfy and almost all the scenes were Okayed after one take."
