Jingle) is a 1991 Indian Malayalam-language comedy drama film directed by Priyadarshan and written by Venu Nagavalli.

The story set in Ooty revolves around tourist guide Joji (Mohanlal) and photographer Nishchal (Jagathy Sreekumar).

It also stars Thilakan, Innocent, K. B. Ganesh Kumar, Sukumari, and Sharat Saxena, with Murali and Jagadish making cameo appearances.

Nandini, a tourist, who is mentally challenged, and a series of events make her presence intertwined with the lives of Joji and his friend Nischal.

The story was developed by Priyadarshan from a thought which came to his mind, about a mentally-ill mischievous girl who is saved by a poor guy.

Amala who was acting in Priyadarshan's Telugu film Nirnayam at the time, was signed for the role of Nandini.

In Ooty, The Fernhills Palace was the central location, which was shot as the bungalow of Justice Pillai, played by Thilakan.

The major part of the filming took place early in the morning because the mist lasted for a couple of hours only and the makers wanted to capitalise the mist-covered location.

One of the initial scenes in the film, where Mohanlal and Thilakan takes morning walks, are shot in a secluded location in Ooty that was accidentally discovered by the team.

A sequence in the song was shot over the top of a moving train, where Mohanlal was standing opposite Jagathi and Revathy.

While performing, all of a sudden, Sreekumar instructed Mohanlal to lie low, which he immediately obeyed without questioning.

In 2012, the executives of Ultra Rays 3D Technologies Private Ltd in Kochi approached Priyadarshan and Ram Mohan for talks for the 3D conversion of Kilukkam.
