Originally, I was hoping to study psychology and serial killers. However, my research advanced and I needed to find a gap. I started to look into film and how serial killers are portrayed in movies versus reality. When researching, I used keywords such as horror movies, and used famous serial killers to create an idea of commonalities. I also researched different kinds of serial killers and their different motives in order to find a system of how to determine reality with serial killers. With further digging, I found a gap between whether females or males are more realistically portrayed in movies, which became my area of study. I found movies in which I will watch and analyze deciding how realistically portrayed the serial killers are within the movies. I picked 10 movies surrounding men, American Psycho (2000), The CloveHitch Killer (2019), Split (2016), The Snowman (2017), Maniac (2012), Perfume (2006), Halloween (1978), Silence of The Lambs (1991), and Scream (1996). As well as 10 movies surrounding female killers, Happy Death Day (2017),  Ma (2019), High tension (2003), Titane (2021), Lady Psycho Killer (2015), Prevenge (2016), Tragedy girls (2017), The Girl Who Got Away (2021), Carrie (1976), Me You Madness (2021). I chose to keep the movie selections within the 1960’s to current day keep some kind of timeline due to the first case of FBI using profiling techniques was in 1960.
