Javed were  not able to sell the script for a long time until director Chandra  Barot and producer Nariman Irani bought it. It was rejected by Dev  Anand, Prakash Mehra and Jeetendra. The script did not even have a  name. It was a script pertaining to a character called Don. When  Nariman Irani approached Salim, he said, Humare paas ek breakfast  script padi hai jo koi nahi le raha hai. And Nariman said  chalega. So that is how Don was made.
