They both met for the first time in 1968. Iyer was about to direct a Kannada film titled Hamsa Geethe. The movie was based on a T. R. Rao novel. Iyer also produced the film. The film starred Anant Nag, Rekha Rao, and B. V. Karanth in the lead. It was released in 1975 and became a massive hit.

The movie was a great success and was awarded the 31st National Film Award by Indira Gandhi (former Prime Minister of India).

He entered the Malayalam cinema in 1987 with the film Swathi Thirunal, directed by Lenin Rajendran. After this film, he worked in the Malayalam cinema for fifteen more films, out of which ‘Perumthachan’, and ‘Veeragatha’ became major hits.
