The song "Panna Ki Tammanah" was sampled in the Punjabi song "Dildarian" by Arminder Gill.
After Zeenat Aman played Dev's sister in Hare Rama Hare Krishna she was flooded with only sister roles. Her mentor Dev Anand stopped her from accepting those roles and launched Heera Panna where she played his heroine. The rest is history. Zeenat went on to become the No.2 heroine after Hema malini and acted with all the top stars during the 1970s and early 80s.
During Heera Panna,R.D.Burman was going through depression, then Dev Anand sat and talked with him for about 3 hours, and then R.D..Burman composed 4 melodios songs of Heera Panna.
The theme of Heera Panna is of that a modern day sophisicated photographer alwaya travelling across and outside the country and the situations he always encounters wherever he goes.
Raakhee had admitted in an interview that her high regard for Dev Anand led her to making special appearances as his love interest/wife in several of his movies. Heera Panna, Joshila, Lootmaar, and Anand aur anand.
