Shammi kapoor said that he also forgot his lines while watching madhubala
This was Shammi Kapoor's last film with Madhubala. He had started his film career with her in the film "Rail Ka Dibba" (1953) and worked with her again in "Naqab" (1955). According to Kapoor, he had been smitten by Madhubala and had even proposed to her. However, the actress was involved with Dilip Kumar at the time and had turned him down. In an interview, Kapoor said that Madhubala would often tell him during the making of "Rail Ka Dibba" (1953) that he was too thin and that he needed to put on weight. However, eight years later, during the making of this film, she told him that he had gotten "fat".
The film's premise was likely inspired by the hit Hindi film "Kismet" (1943). Amirbai Karnataki, who sang several songs in the 1943 film, played the mother of Shammi Kapoor's character in this film.
Dharmendra's only film with a young clean shaven and slim Shammi Kapoor.

The mukhda of this song had the words "phir dekho maza pyar ka" in the 78 rpm records. This line was replaced by "phir ho jaoon sansar ka" in the film due to the Censor Board's objection.
