After his directorial debut
Agaya Gangai (1982) failed,
Manobala did not get any further offers to direct which left him depressed and he contemplated suicide.
P. Kalaimani approached Manobala to direct a film for him which was titled
Muthal Vasantham; however the partners of Kalaimani were uninterested in having Manobala as director and replaced him with
Manivannan. Despite this Kalaimani promised Manobala to direct a film which eventually became
Pillai Nila. The film took inspiration from various horror films such as
Christine (1983),
Poltergeist (1982),
The Omen (1976) and
The Exorcist (1973). The makers sought to avoid clichéd horror film tropes such as
haunted houses, "sex-charged teenagers" and "unrealistic monsters in rubber masks". == Soundtrack ==
