Finally a horror film down South that is terrifying! Okay, most horror films down South are terrifying but I recently saw Kaashmora and it was anything but scary. But coming back to Katerri, the story revolves around a novel and how everything written in it is actually true. You'll have to keep confusing the ghost and make sure you don't give either a right or a wrong answer to its questions. The teaser is so scary, we bet you'll find it difficult to sleep tonight. And quite literally, because the teaser has a scene where a saadhu asks the victim to keep looking at the ghost in front of him WITHOUT BLINKING!

Though the novel also seems to have a solution to the ghost problem but fear can get the best of its victims. The film stars Varalakshmi Sarathkumar, Vaibhav, Sonam Bajwa and Aathmika. It has been directed by Deekay and it does promise you a scary ride. If you are someone who binge watches horror films, you'll definitely love this. Though a couple of scenes might be inspired from Hollywood films. Since I watch a lot of Doctor Who, I could instantly relate the "Don't Blink" scene with an episode from the series that had the weeping angels.

Check out the teaser right here.

Scary, isn't it? We wonder how scary the trailer of the film is going to if the teaser itself is this scary. Fans have also given the teaser a thumbs up and can't stop raving about it on social media and in the comments section of the video. The release date of the film is yet to be out.
