Naalum Therindhavan was released on 12 December 1968. The Indian Express wrote, "There is a sequence and an important one that takes place in complete darkness. All one can hear is the noise of charactersrunning about and stumbling over things. Spectators are puzzled as to what is happening on the screen during these minutes. And they are equally puzzled at what is shown in sparklingbrightness for they can't make head or tail out of this mumbo-jumbo, running to 16 reels."
