Unarchigal
Unarchigal is a 1976 Tamil language film directed by R. C. Sakthi starring Kamal Haasan and Srividya in the lead roles. It is a highly sensuous film which deals with sexually transmitted diseases, and subsequently the film ran into trouble with the censor board prompting a delay in its release.
The film was initially supposed to be Kamal Haasans first movie as a lead actor after being launched in 1972, however delays meant that the film was only releasedyears later. The same film was later remade in Malayalam as Raasaleela and released in 1975, before the original had come out.
