The song of this movie "Mera joota hai jaapani" is heard being played in the opening seen of Dead pool (2016).
Three year old Rishi Kapoor made an appearance in the song Pyar Hua Ikraar Hua alongside siblings Randhir Kapoor and Ritu Kapoor.He would cry continuously whenever water got spilled on him and it would get difficult to shoot him.Nargis then took Rishi Kapoor to a room and bribed that if he keeps his eyes open and wont cry after water spills on him scene she will give him a chocolate.
Ramaiya Vastavaiya in Telugu means Lord Ram Will Come To You.The title alone is derived from an old Telugu folk song.
In one scene of the song, Pyar Hua Ikraar Hua.....' Raj Kapoor's children, Ritu, Randhir and Rishi, were seen wearing raincoats. Nadira got a good role. After this film Raj Kapoor was to make a film called Ajaanta. and even Hasrat Jaipuri wrote a song and Shanker-Jaikishan worked out a tune, the song was. Sun Saiba Sun...... but then Ajaanta was shelved, instead Aah. was made and that Hasrat Jaipuri song was then used, after 30 years, in Raj Kapoor's last directed film, Ram Teri Ganga Maili.
