Kamleshwar wrote the script and the dialogues were written by Inder Raj Anand.

Mohammed Rafi dint get the chance to sing all the song and his remaining songs were sung by Anwar.

The producers first produced Duniya Meri Jeb Main then Yeh Ishq Naheen Aasaan then Shahenshah.

Character actors Om Prakash and Ifthekaar had very important role in the film.

Yeh Ishq Naheen Aahsaan dint get proper release.

Only movie to star Deepti Naval in a romantic role opposite Rishi Kapoor. Years later they were paired opposite each other in Aurangzeb.

This was the third movie of Rishi Kapoor and Padmini Kolhapure together after the movies Nasir Hussein"s Zamane Ko Dikhana Hai and Raj Kapoor"s Prem Rog. Pyar Jhukta Nahin would have been the fourth one if Rishi Kapoor had done the movie as he was offered before Mithun Chakravorty.

Deepti Naval was newcomer when she signed this movie.

In Zamane Ko Dikhana Hai & Yeh Ishq Nahin both films had Padmini Kolhapure and Yogeeta Bali had important roles.

Tinnu Anand stated he started the film to recover from the losses of Duniya Mere Jeb Mein. But the film was even a bigger disaster.

This film was the second production of Tinnu Anand, Bitu Anand and Naresh Malhotra after their maiden Duniya Meri Jeb Main. The third was Shahenshah which was their third and the last work of Inder Raj Anand.

Veterans like Agha, Sunder, Ifthekhar, Murad, Om Prakash, Mumtaz Begam, Leela Mishra were part of this film.

Tinnu Anand"s father in law Agha and his brother in law Jalal Agha, they appeared in the film as friendly appearance.

The major writer Inder Raj Anand, his sons made this film.

One of the rare commercial films where Deepti Naval played a lead role. This film was made in 1982 but due to the debacle of Deedar e Yaar which was also a muslim social like Ye ishq nahi aasan , the film was delayed and got a release in December 1984. By that time Rishi Kapoor and Padmini both were down with continous flops. And therefore this film couldn't make a mark at the box office
