It was during the movies shooting Dilip Kumar first met Sanjeev Kumar. After doing a intense scene with Sanjeev Kumar, the director called for lunch break. It was during lunch that Dilip Kumar asked the director " Where did you find that old man ?(Sanjeev). He is such a good actor. He was quite surprised!". That is when the director had a good laugh and told Dilip that Sanjeev was wearing make up and actually was only 29.
Raaj Kumar was signed for the film but later replaced by Sanjeev Kumar.
This film had major powerful actors besides Dilip Kumar like Balraj Sahni, Jayant and Sapru. Sanjeev Kumar was a new comer when he acted in this film.
