To think of it, I think this film could be just like Pithamagan, but in a different dimension though. the resemblances are interesting. The Lord Shiva link (Pithamagan had link to Lord Shiva.... the burialground link). The rustic, uncouth type of character seems to be common in both films, although in this film it might take a diferent dimension.
ofcourse story will be totally different..but looks like the director took off in an alternate plane, while concieving this film.
