Tuney yeh rangeele kaisa jadoo kiya" (Kudrat) sampled from Bengali song "Haay ki kori mano niya".
The lyrics of the song "Tune Kaisa Jaadu Kiya" in Himalay Putra was similar to the song "Tune O Rangile Kaisa Jadu Kiya" from Kudrat.
The second movie where Rajesh Khanna and Hema Malini played 'reincarnated' lovers. Mehbooba released in 1976 was the first.
The film started in April 1979 and was getting delayed for several reasons. Actor ego's, Priya Rajvansh working caliber, dates going haywire. By December 1980 the film was mid ready. Thats when Chetan Anand did something unexpected. He drew up a contract and wanted B.S. Khanna to sign it. Khanna felt helpless at this point. If he did not sign the contract the film would have been left incomplete. The first clause was the film would be advertised as a Chetan Anand film The second clause was Chetan Anand would have the final say in everything. Right up to the film going to the censor board. Chetan then added the clause his fees would be paid in full and up front. Khanna stated he acted under duress. Khanna sought advise from the Producer's Association (IMPPA) and signed the agreement.
