Filmmaker R. Balki recalled Rajesh Khanna's professionalism and humor during the shooting of his final advertisement for a fan brand. Despite his declining health and need for an air ambulance, Khanna displayed dedication and wit, even joking about his diminished superstardom. The ad, released posthumously, featured Khanna reminiscing about his fans and humorously concluding he still had Havells fans, with background fans blowing wind on him.
