Chintamani is a 1937 Indian Tamil-language film directed by Y. V. Rao starring M. K. Thyagaraja Bhagavathar, Serugulathur Sama and Aswathamma.

In 1937, a Tamil version of the film was directed by film-maker Y. V. Rao under the banner of Rayal Talkies, owned by yarn merchants of Madurai.

[7] Chintamani was based on the legendary story of a Sanskrit poet and devotee of Lord Krishna named Bilwamangal (M. K. Thyragaraja Bhagavathar).

Bilwamangal, a resident of Varanasi, was a Sanskrit scholar, who gets infatuated towards a courtesan called Chintamani (Aswathamma), a woman of ill-fame.

[6] With the substantial profits obtained from the movie, the owners of Rayal Talkies constructed a theatre in Madurai and named it Chintamani.

[6] The gramophone discs of Chintamani were also popular though M. K. Thyagaraja Bhagavathar did not sing the songs that were featured in them as he was not under contract with Saraswathi Stores which produced the records.

Thyagaraja Bhagavathar who has played Bilwamangal has shown his acting and singing talents[10] The soundtrack was composed by Papanasam Sivan.
