He started his career at the age of eight when he joined the Gubbi Veeranna theatre group.[5] His first role as an actor in cinema was in the film Radha Ramana. Besides this he acted in a number of other movies such as Mahakavi Kalidasa, Sodhari, Hemavati, Hari Bhaktha and Bedara Kannapa. He is credited with providing breaks to two of the greatest Kannada actors, Dr. Rajkumar and Narasimha Raju in the movie Bedara Kannappa. Though Raj Kumar had acted in a single scene in a movie previously, the movie Bedara Kannappa where Mr Iyer cast him as the hero, is where he got his break and is regarded generally as his first movie. Iyer also produced the critically acclaimed movie Vamsha Vriksha. Based on an acclaimed novel by S L Bhairappa, it was jointly directed by B V Karanth and Girish Karnad.
He soon started directing his own movies. The movie Hamsageethe (music by Dr. Balamuralikrishna, B. V. Karanth and T.G. Lingappa) was well received and made him famous. Iyer wrote scripts, lyrics and produced and directed many commercial Kannada movies. Iyer's biggest effort was Ranadheera Kanteerava. He continued to make commercial movies until 1970.
In his younger days, he was committed to Gandhi and his ideals. He stopped wearing footwear from the day Gandhi died and never wore them again. He also wore hand-spun clothes colloquially called "Khadi" as was advocated by Gandhi.
He produced Natyarani Shanthala, a historical television series on the HoysalaJain queen Shanthala, who was married to a Vaishnava King. It was re-made in Hindi as well as in Kannada. It was based on several works by Samethanahalli Rama Rao in Kannada.
He was planning a film based on the Hindu epic Ramayana, with Sanjay Dutt playing the role of Ravana, before his sudden death on 21 December 2003 at the age of 87. His last rites took place at his Bharadhwaja Ashrama, near Dodda Aladamara, on the outskirts of Bangalore, near Kengeri.[1][7]
