Jupiter Pictures partner Somu asked
A. S. A. Sami to create a screenplay that he himself could direct with artistes on the payroll of the company. However, when he read Sami's screenplay, he suggested that
P. U. Chinnappa and
T. R. Rajakumari, who were in the forefront at that time, play the lead roles. But Sami requested Somu to stick to the original decision.
M. G. Ramachandran (then credited as Ramachandar) and Malathi were asked to play the lead roles. After more than half the film was shot, the company's other partner S. K. Mohideen felt the project be abandoned. Somu weighed the consequences in the light of future career of Sami and Ramachandar. He told his partner that a decision could be taken on completion of the film.
K. Thavamani Devi who was a talented dancer and singer played the role of a vamp. At one point she came for shooting wearing a dress with a plunging neckline (something unseen those days). It caused ripples on the set. For a scene, where Nambiar who becomes invisible and follows Swaminathan, Sami revealed it was inspired from
The Invisible Man. == Soundtrack ==
