In 2012, Films Division produced a 93-minute film on BV Karanth called BV Karanth:Baba Directed by Ramchandra P.N. The film bases itself on BV Karanth's autobiography in Kannada called Illiralaare, Allige Hogalaare (I can't stay here, I won't go there) compiled by well known Kannada writer Vaidehi. ಇಲ್ಲಿರಲಾರೆ ಅಲ್ಲಿಗೆ ಹೋಗಲಾರೆ, ಬಿ.ವಿ. ಕಾರಂತ ಬದುಕಿನ ನೆನಪು ಅನುಭವಗಳ ಕಥನ ಆಧರಿಸಿದ ಸಾಕ್ಷ್ಯಚಿತ್ರ.
Karanth directed over a hundred plays, more than half of which were in Kannada with Hindi close behind. He also directed plays in English, Telugu, Malayalam, Tamil, Punjabi, Urdu, Sanskrit and Gujarati. Hayavadana (by Girish Karnad), Kattale Belaku, Huchu Kudure, Evam Indrajit, Oedipus, Sankranti, Jokumara Swami, Sattavara Neralu, Huttava Badidare and Gokula Nirgamana are some of his most popular plays in Kannada. Of the forty or so plays he directed in Hindi, Macbeth (using the traditional Yakshagana dance drama form), King Lear, Chandrahasa, Hayavadana, Ghasiram Kotwal, Mrichha Katika, Mudra Rakshasa, and Malavikagni Mitra are some of the more popular ones. Karanth also revelled in directing children and directed several children plays like Panjara Shale, Neeli Kudure, Heddayana, Alilu Ramayana and The Grateful Man.

In 1974, Karanth started BeNaKa a repertory in Bangalore. Benaka was an acronym for Bengalooru Nagara Kalavidaru. Benaka stages several hugely popular plays like Hayavadana all across Karnataka and even overseas. At Benaka, Karanth also took a special interest in children's theatre and directed several plays with children. This group has been taken care of by Prema Karanth, Karanth's late wife and a noted theatre personality in her own right. She died on 29-10-07.
Karanth was largely responsible for starting the new theatre movement in Madhya Pradesh. As director of the NSD, at the invitation of the Bharat Bhavan in Bhopal, he organized a training-cum-production camp in 1973. In the 1980s, he returned to set up the Rangmandal repertory in Bharat Bhavan. This was to be the first-ever repertory in the state and he became the main creative spirit behind the now-legendary Bharat Bhavan.
