Release and reception
Sattam Oru Vilaiyattu was released on 21 October 1987, alongside another Vijayakanth film Uzhavan Magan. However, both films went on to become super hits at the box office. The Indian Express wrote, "The screenplay is utterly contrived and there is nothing new either in M. Karunanidhi's dialogues [..] or S. A. Chandrasekhar's treatment which is as hackneyed as ever".
