Don is a 1978 Indian Hindi-language action thriller film directed by Chandra Barot from a story written by Salim–Javed and produced by Nariman Irani.

Don was the third highest-grossing Indian film of 1978 and was classified a golden jubilee by Box Office India.

The intro "Yeh Mera Dil" was sampled by the Black Eyed Peas for the song "Don't Phunk with My Heart" (2005).

[5] Don is a notorious crime boss in Mumbai who always eludes the authorities despite being wanted in eleven countries.

DSP D'Silva, Inspector Verma and Interpol officer R. K. Malik have spent the last few years in capturing Don, but to no avail.

D'Silva keeps Don's death as a secret even from his fellow officers, and tracks down a look-alike called Vijay, a street performer.

Unable to prove his innocence, Vijay escapes from a police van and joins Roma, where he learns that the diary is stolen by a person named Jasjit in order to track down his children Deepu and Munni.

After being captured by Vardhaan, Jasjit is reunited with Deepu and Munni and manages to escape the hideout with them, thanking Vijay for taking care of his children.

Eventually, Vardhaan calls Inspector Verma and the police to the scene to have the trio and the gang members arrested so that he can get away scot-free.

Vardhaan and the gang members are arrested, while Vijay, Roma, Jasjit, Deepu and Munni happily leave the police station.

When he was doing the cinematography for Manoj Kumar's major hit Roti Kapada Aur Makaan (1974), the film's cast (Amitabh Bachchan, Zeenat Aman, Pran) and crew (assistant director Chandra Barot) decided to help him out.

They all approached scriptwriting duo Salim–Javed (Salim Khan and Javed Akhtar), who gave them an untitled script that had already been rejected by the entire industry.

[12] Kishore Kumar and Asha Bhosle received accolades at filmfare for the tracks "Khaike Paan Banaraswala" and "Yeh Mera Dil" respectively, both of which have also been remixed in the remake.
