Filmmaker Karan Johar has a lot of information about everything that was happening on the film sets back in the 1960s and 1970s, courtesy, his late father Yash Johar. He recently revealed that his father was present on the sets of various films, including K Asif’s monumental film Mughal-E-Azam (1960). The senior Johar told his son about one of the days when Mughal-E-Azam was being shot and suddenly K Asif announced pack-up and didn’t resume shooting for the next three days.During an interaction with Film Companion, KJo said, “My father was on the sets of Mughal-E-Azam. I have voluminous information of the things that were happening on the set at that time, the dynamic between actor and director, actress and director.”Karan shared that though the production team had filled the pond with water “like anybody would do”, K Asif was not happy and didn’t agree to shoot until ‘ittar’ was arranged. “It’s a production requirement, you can’t fill in a pond full of real ittar. They said they would take three days to fill it with ‘ittar’. He packed up and didn’t shoot for three days until that pond was full of ‘ittar’,” Karan shared.K Asif started the process of making this film in 1944 and took 16 years to complete it.
