Feroz Khans role was first offered to Raj Kumar.
Feroz Khan won the Filmfare award for Best Supporting Actor for Aadmi Aur Insaan.
Raj Kumar refused the film for several reasons . He refused a scene where Dharmendra was to slap him. Feeling the scene was insulting to him by getting slapped by a actor who was junior to him.
Raaj Kumar refused to do a scene where he had to put a garland around Dharmendra' s neck. This is another reason he refused to do the film.
As this film was delayed, in between of this film the makers made Ittefaak, than later Admi Aur Insaan was completed.
