FLAMBOYANT KISHORE KUMAR
The film Anand (1971) was originally supposed to star Kishore Kumar and Mehmood in the lead roles. Hrishikesh Mukherjee, the director of the film, was asked to meet Kishore Kumar to discuss the project. However, when he went to Kishore Kumar's house, he was driven away by the gatekeeper due to a misunderstanding. Kishore Kumar (himself a Bengali) hadn't been paid for a stage show organized by another Bengali man, and had instructed his gatekeeper to drive away this "Bengali", if he ever visited the house. When Hrishikesh Mukherjee (also a Bengali) went to Kishore Kumar's house, the gatekeeper drove him away, mistaking him for the "Bengali" that Kishore Kumar had asked him to drive away. Consequently, Mehmood had to leave the film as well, and new actors (Rajesh Khanna and Amitabh Bachchan) were signed up for the film.
