At his peak, Krishan was called the King of Madras (Chennai's old name) - and with good reason too! The man whose first car came as an appreciative gift from his Badi Behen
producer had a good knowledge of Tamil, which made him the obvious choice as scriptwriter for remakes into Hindi - a trend that was more rampant from the '50s to the '70s than it is today!
The genius usually reworked these scripts and penned the Hindi dialogues with a pan-Indian appeal, and among such blockbusters were Nazrana, Rakhi
(produced by South titan Sivaji Ganesan), Shaadi, Main Chup Rahungi, Waris, Gopi
and of course the classic Pyar Kiye Jaa
. Even in Mumbai, the master-writer scripted films like Albela, Nagin, Padosan, Bombay To Goa
and others. His last film was Aag Ka Darya
, whose audio was out in 1995, but the Dilip Kumar-Rekha film never could release in the theatres.
Though he never formed a prolific team with any specific composer, Krishan's most frequent association is said to be with Madan Mohan. But the man spun hits with generations of composers, from Husnlal-Bhagatram, Shyam Sunder and Anil Biswas to C.Ramachandra and later Hemant Kumar, Madan Mohan, S.D.Burman, Chitragupta, Ravi, Shanker-Jaikishan, Salil Chowdhury and finally Kalyanji-Anandji, R.D.Burman and Laxmikant-Pyarelal.
