On the other hand, this presentation shows us what kind of lighting to use for thriller movies. Since lighting is a big part of thriller and horror movies, establishing that feel into the movie is very important. For example, using a low-key lighting helps create that feel of danger and mystery to the movie, which most cases that's what one will be working with when it comes to thriller movies. Top lighting is also great when you want to create a mysterious creature and you have a light coming from the top of the creature which only gives us a small look at that creature. Lighting is one of the most important traits of a thriller, but it also makes it one of the hardest traits since it has to be performed perfectly.
