The maker of this film, H.S.Rawail, wanted Sadhna to have different look in the film, so he took scissors, cut some hair on Sadhna forhead and then formed the famous Sadhna cut. Orgionaly this film was tittled. Mehboob later 'Mere' was added to the tittle.
H.S.Rawail wasn't satisfied with the tittle song sung by Mohammed Rafi as there was very minimum music and very less Orchestra during the recording of the song. Music composer Naushad convinced him that this song is ok and will be a big hit and really was a big hit after release.
During the song sequence of ae husn zaara ishq......the focus was more on Sadhna than Rajendra Kumar.
There was a urban legend that at the premiere of Mere Mehboob a mysterious lady draped in a burqa gate crashed the party .The mysterious lady thrust in Sadhana's hands a pudi (mint) containing some leaves. She told Sadhana she looked very beautiful in the movie. A week later Sadhana became very ill and started having her thyroid problem and depression. It was then said that the mysterious lady had done black magic on the leaves and cursed Sadhana. Sadhana was never the same after that night .
This movie was released immediately after Eid 1963. The song.the story and the best music from the legendary naushad all combined to give this a massive success and set the cash registers burning.....The producer's tried to make another movie with the same outlook after few years but failed
