Thriller is a genre of film that uses suspense, tension, and excitement as the main elements. There are many Thriller sub-genres such as crime, mystery, political , supernatural etc. However psychological thrillers are interesting me most at the moment. The best psychological thrillers are packed with suspense and have elements of mystery, drama and deception. I find them interesting as they tend to focus more on the plot, the twists in the plot can take you from complete comprehension to complete confusion, keeping you gripped to the screen.
Alfred Hitchcock, who is considered the master of suspense, made several amazing psychological thrillers. Below are some examples of his work that first interested me in the sub-genres:
Alfred Hitchcock's Psycho is the 'mother' of all suspense film, and has influenced many other thrillers.
Strangers on a Train (1951)
The Man Who Knew Too Much (1956)
Dial M for Murder (1954)
