Jeetendra did a small appearancence in the song "yeh jo public hai". In real life jeetendra and Rajesh khanna were good friends and it was Rajesh Khanna who helped Jeetendra for his debut.
After listening the script from Kadar Khan Manmohan Desai gifted him a Television and a watch and asked him how much does he charge to write a story.Kadar Khan said 21000.Manmohan Desai told him from today your price is one Lakh twenty one thousand.
One of Rajesh Khanna's last blockbusters in his glory period.
While working on the film Manmohan Desai came to know about a middle aged talented writer named Kadar Khan.He called him and asked to write the script after completing the script he went to meet Manmohan Desai who asked him to read the script again and again Kadar Khan was confused why was he asking him to read the script again and again.Kadar Khan realized that Manmohan Desai was trying to explain him that he should get more and more better in every thing he is doing.This created a never ending association of them both.
Shatrughan Sinha claims Manmohan Desai promised him the lead role. They had done Rampur Ka Lakshman and Manmohan Desai felt it Shatrughan deserved all the credit. But Manmohan Desai was going to get more money from the distributors if he had Rajesh Khanna in the film. That is when Shatrughan was dropped from the film.
