Andhaman Kaidhi was a play written by Ku. Sa. Krishnamurthy, first staged in 1938. When it was adapted into a film produced by Radhakrishna Films, Krishnamurthy was retained as screenwriter. The film was originally directed by K. Subramanyam who left, resulting in cinematographer V. Krishnan taking over direction.^[2] Newsreel footage of Indian Independence Day celebrations was added to the beginning of the film.^[3] M. G. Ramachandran was credited by his real name, rather than "Ramchandar" that was prevailing in many of his previous films in the late 1940s.^[4]

The music was composed by G. Govindarajulu Naidu. All the lyrics were by Ku. Sa. Krishnamurthy except the song "Kaani Nilam Vendum Paraasakthi", based on a song written by poet Subramania Bharati.^[5][6][7] The song "Anju Rooba Nottai Konjam Munne Maatthi", sung by T. V. Rathnam, revolves around the poor masses who suffer from economic disparity.^[2]

Andhaman Kaidhi was released on 14 March 1952.^[8] According to historian Randor Guy, the film was not a major success but helped Ramachandran "move up the ladder of success".^[2]
