Producer
S. S. Vasan's son-in-law G. S. Mani sought to remake the American film
The Sound of Music (1965) in Tamil and asked
Chithralaya Gopu to write the screenplay for the Tamil version, then present it to Vasan as a surprise. Although Vasan liked the screenplay, he felt that the film would not cater to rural audiences, so it was rewritten to be closer to the
Charlotte Brontë novel
Jane Eyre (1847). The film was Mani's directorial debut. Cinematography was handled by
Marcus Bartley, and editing by Umanath. Gopu's recommendation of
Kanchana for the lead role was agreed upon by Mani. The film was entirely shot at
Ooty and Mohana Kumari was in charge of the art direction. Camera techniques were used in the song "Bhoomiyil Iruppadhu" to show that a helium balloon was flying, while in reality it was not. == Soundtrack ==
