Today: O is for Obsession

And so, today The A-Z of Horror has arrived at obsession – one of the driving forces behind many a good horror movie and/or series.

From Hannibal Lector to Jason Voorhees, there are countless killers who love nothing more than an obsession – either obsessing over a victim or an obsessing over murder. Not only does this obsession give the character motivation, but it also provides them with an endless excuse to do the same thing over and over again in subsequent sequels.

Below are three of the best films about obsession. Each entry features a character who is just as dangerous as Michael Myers or Leatherface, and this is because their obsession consumes, engulfs and intoxicates them.

One Hour Photo (2002) – Featuring a stand-out performance from Robin Williams, One Hour Photo is an intriguing tale of one man’s obsession with a family he longs to be a part of. Williams plays, Sy ‘the photo guy’ Parrish, a photo technician who creates a life and a sense of belonging through the photos he develops for strangers. But when that life is threatened, Sy has to do his level best to keep all the pieces in play.

Misery (1990) – Another stand-out performance, but this time via Kathy Bates as the unhinged Annie Wilkes in Misery. Wilkes is the self-professed ‘Number 1 fan’ of writer, Paul Sheldon and when the pair cross paths, Wilkes’ obsession takes a turn for the worse.

Fatal Attraction (1987) – Glenn Close steals the show as Alex Forrest, a publishing editor who becomes obsessed with Dan Gallagher (Michael Douglas), a married man who she engages in an affair with. Over a short period of time, Alex’s obsession hardens and when faced with rejection from Dan she decides to descends down a path with only one exit – death!

Wow! I said they were obsessed. These three films are not only great examples of the obsession subgenre, but are also great films in general. If you’re looking for horror movies to become obsessed with, here’s where to start!
