Raj Kapoor was very fond of Rajesh Khanna as an actor and asked him if he would like to come on board of ‘Satyam Shivam Sundaram’. Kakaji (as Rajesh Khanna) was fondly called and agreed soon enough. But Team ‘Satyam Shivam Sundaram’ was not in favour of casting Rajesh Khanna. They told Raj Kapoor to cast Shashi Kapoor instead.
Next, Raj Kapoor broke this news to Rajesh Khanna on his birthday, which falls on December 29 (today also is December 29). Rajesh Khanna told him not to worry.
Destiny is funny and many years later, Rishi Kapoor approached Rajesh Khanna to play Akshaye Khanna’s father in his directorial ‘Aa Ab Laut Chalein’. Rajesh Khanna signed the role and sometime after he had confirmed his availability on the film, he told his dear friend Bhupesh Raseen ‘Aaj neele aankhon wale (he meant, Raj Kapoor) jab yeh dekh rahe honge (from heaven), toh woh zaroor muskura rahe honge’!
When contacted, Bhupesh Raseen confirmed the story.
