Even before you begin watching the trailer, the makers warn you that there is frightening imagery and that you will have to consume the content in your own risk.

And if you are among the weak-hearted, you should run at this very point.

For the rest of you brave enough to go ahead, the trailer of Aval starring actors Siddharth and Andrea Jeremiah leaves your heart pounding for a while after the two minute video ends.

It doesn't help your nerves that the trailer begins with a shot of a human brain and a stunned Siddharth seconds later. But to make things spookier, they tell you that the movie is based on a true story. That is when you realise you need to brace yourself for the worst.

What follows next is a series of horrific incidents all surrounding a particular mansion in a hill station, where Andrea and Siddharth, a married couple, live. We are introduced to Jenny and her daughter Sarah and it seems the mother is the one who is possessed.

Bollywood actor Atul Kulkarni makes an appearance too and looks frightened for the most part. But it is a brief appearance by the ghost or monster that haunts the building that really leaves you frightened. The music by Girish Gopalakrishnan of Marina fame, as expected from a horror film, amplifies the terror. 

Directed by Milind Rau and produced under Siddharth's home banner, it seems likely that this film which is set to release on November 3, will scare the living daylights out of you.
