The parts of the song Aa Zara Mere Hum Nasheen was later used by Anu Malik once again in the song Tu Fiza from the film Fiza and Chori Chori in the film Kareeb.
Poonam Dhillon did not like the film's title. She felt uncomfortable with a film named after her real name. She kept requesting the director to change it. Harmesh told her he would change th3 title provided she found a good alternative title.
Poonam is Anu Malik's first big major project. He even got the chance to work with Legends Mohammed in this film and Hasrat Jaipuri wrote the songs
Producer and Director Harmesh Malhotra was the first mojor Filmmaker who gave Anu Malik major break with this film. Infact Harmesh Malhotra took Anu Malik for 4 films at one go, Poonam, Aapas Ki Baat, Mangal Pandey & Phaansi Ki Baat. Actually Mangal Pandey was started before, later Poonam started and completed released, Mangal Pandey was released later.
The parts of the song "Aa Zara Mere Hum Nasheen" from Poonam was later used by Anu Malik once again in the song "Tu Fiza Hain" from the film Fiza and "Chori Chori Jab" in the film Kareeb. The original source seems to be the bell chime tune in the Zanjeer (1973) Title music. Zanjeer's Title music was sampled from Jerry Goldsmith's "The Last Run" main title music. Other version's of the song are Eija Merila's "Viimeinen mahdollisuus" and Tapio Liinoja's " Viimeinen mahdollisuus".
