The first time we see Ganga as Nagavalli, in all her 'finery', Manichitrathazhu (1993)
Nagavalli, or Ganga as Nagavalli, barely gets 10 minutes of screen time in the film. Which means that when we see her face for the first time during "Oru Murai Vanthu Parthaya" after several wide shots, Shobana eclipses what we've imagined to be this bloodthirsty spectre. And it's suddenly all types of fear taking over the viewer's body.
The first kill, Bhoot (2003)
The most chilling scene comes when Vishal (Ajay Devgan) is smoking a cigarette by the window, looking at the rain and Swati (Urmila Matondkar) quietly sleepwalks into the frame in the background, opens the door, exits. Vishal doesn't realise till he finishes his smoke and notices the door open.
Remember the Name, Tumbbad (2018)
It begins with a freak accident, that has no explanation, just bad omen. Vinayak's (Dhundiraj Prabhakar Jogalekar) brother, Sadashiv (Rudra Soni), has a fatal fall from a tree. That night is going to be the most terrifying night of Vinayak's life.
Lagoon Creeps, Kumbalangi Nights (2019)
This scene is proof that terror needn't always rise from blood and gore and alien beings and ghosts. It can be shirtless, in a lungi, in the form of Fahadh Faasil and still scare the shit out of you.
An Unholy Communion, Pari (2018)
There is a two-and-a-half minute sequence when Arnab (Parambrata Chatterjee) is rummaging through a great old book in a library, finding out more and more about the Ouladhchakra, a satanic cult that hosts this unholy ritual where Ifrit impregnates women with his demon babies in order to spread his bloodline.
