Kathavarayan is a 1958 Indian Tamil-language Hindu mythological film produced and directed by T. R. Ramanna, and written by Thuraiyur K. Murthy.

Kathavarayan grows up and goes on a world tour, his mother Shakti blesses him with the divine power of transforming into any form he wishes when he is in danger.

[2] The original lead actor was M. G. Ramachandran, who withdrew due to creative differences with Ramanna, resulting in Sivaji Ganesan replacing him.

[3] To differentiate Kathavarayan from Aryamala, Ramanna added a number of song and dance sequences.

[2][7] Kumudam, in its review, gave the film a single line remark: "Kattharavaayan" (a pun on the film's title and the Tamil word for shouting, /kəθθə/), reflecting on how it looked like a photographed play with most of the focus on aggressive dialogue delivery, similar to Parasakthi (1952).
