The film has no title cards. Instead the titles and credits are narrated using a voice over by Amitabh Bachchan.
Rajesh Khanna wears a cap throughout the film, never exposing his full hair even once.
Super star Rajesh Khanna played the title role and did not have a romantic lead opposite him for the second time after the successful Anand (1971). After this he did an extended special appearance in Anuraag and again had no romantic lead opposite him. Bold considering his super star status.
Amitabh Bachchan was a regular visitor on the sets as he was dating Jaya at the time. Rajesh Khanna would constantly ridicule Amitabh and insult him. One day Rajesh Khanna called Amitabh "manhoos". Jaya upon hearing this finally had enough. She went within Khanna's earshot and said " One day the world will see where this man (Amitabh) will be and where Rajesh Khanna will be."
Inspired by Bengali movie 'Golpo Holeo Sotti (1966)' by Tapan Sinha.
