Annadurai was known as one of the best Tamil orators during his time. He developed a style in Tamil public speaking using metaphors and pleasing alliterations, both in spoken and written language. Anna was also best known for his extempore speaking ability being very well affluent on rhetoric skills.

He has published several novels, short stories and plays which incorporate political themes. He himself acted in some of his plays during his time in the Dravidar Kazhagam.
He introduced movie media as a major organ for propaganda of Dravidian politics. In total Annadurai scripted six screen plays.

His first movie "Nallathambi" (Good Brother, 1948) which starred N. S. Krishnan promoted cooperative farming and abolition of zamindari system. His novels such as "Velaikaari" (Servant Maid, 1949) and "Or Iravu", which were later made into movies, carried the hallmarks of propaganda for Dravidian politics. On "Velaikari", Annadurai said that the movie 
"Velaikari" made direct references against the suppressive landlords who were traditionally allied with Jawaharlal Nehru and Gandhi. His movies had some elements of Dravidian political ideologies like anti-Brahminism and messages differing against Congress with detailed reasons and scenarios behind. Popular stage and cine actors who stood by Anna in early years were D. V. Narayanasamy, K. R. Ramasamy, N. S. Krishnan, S. S. Rajendran, Sivaji Ganesan and M. G. Ramachandran.

Some of his books had a social approach and its content were debatable, such as "Arya Mayai" (Aryan Illusion) in which he highlighted the view point of bringing an equal living society regardless of any caste dominance and especially drawing similarities which existed by then of the upper-caste Brahmin (Aryan) people. He was fined INR 700 for sedition and was also sent to prison.

Some of his well-known works are his books "Annavin Sattasabai Sorpolivukal" (Anna's speeches at the state legislative, 1960), "Ilatchiya varalaru" (History of Principles, 1948), "Valkkaip puyal" (Storm of life, 1948) and "Rankon rata" (Radha from Rangon). His work Kambarasam criticises Ramayana of Kamban. His works of fiction such as "Kapothipura kathal" (Love in the city of Blind), "Parvathy B.A.," "Kalinga rani" (Queen of Kalinga) and "Pavayin payanam" (Travels of a young lady) carried elements of political propaganda.

At times when Dravida Munnetra Kazhagam was extensively using movies for its propaganda, censorship crippled the process. To evade censorships, DMK movies used Annadurai's popular nickname "Anna", which also means elder brother in Tamil, as a pun. When praises were bestowed on the "Anna" on screen, the crowd would break into applause. Kannadasan has criticised Anna's works that apart from "Sivaji Kanda Hindu Rajyam" and "Needhi Devan Mayakkam", the rest lacked even a plot
