Psychological thriller: In which (until the often violent resolution) the conflict between the main characters is mental and emotional, rather than physical. Characters, either by accident or their own curiousness, are dragged into a dangerous conflict or situation that they are not prepared to resolve. Characters are not reliant on physical strength to overcome their brutish enemies, but rather are reliant on their mental resources, whether it be by battling wits with a formidable opponent or by battling for equilibrium in the character's own mind. At times, the characters attempt solving, or are involved in, a mystery. The suspense created by psychological thrillers often comes from two or more characters preying upon one another's minds, either by playing deceptive games with the other or by merely trying to demolish the other's mental state. The Alfred Hitchcock films Suspicion, Shadow of a Doubt, and Strangers on a Train and David Lynch's bizarre and influential Blue Velvet are notable examples of the type, as are The Talented Mr. Ripley, The Machinist, Don't Say A Word, House of 9, Trapped, Flightplan, Shutter Island, Secret Window, Identity, Red Eye, Phone Booth, Psycho, The River Wild, Nick of Time, P2, Breakdown, Panic Room, Misery, Straw Dogs and its remake, Cape Fear, The Collector, Frailty, The Good Son and Funny Games.
Spy thriller: In which the protagonist is generally a government agent who must take violent action against agents of a rival government or (in recent years) terrorists. The subgenre usually deals with the subject of fictional espionage in a realistic way (such as the adaptations of John Le Carré). It is a significant aspect of British cinema, with leading British directors such as Alfred Hitchcock and Carol Reed making notable contributions and many films set in the British Secret Service. The spy film usually fuses the action and science fiction genres, however, some spy films fall safely in the action genre rather than thriller (e.i. James Bond), especially those having frequent shootouts, car chases and such (see the spy entry in the subgenres of action film). Thrillers within this subgenre include Spy Game, Hanna, Traitor, Tinker Tailor Soldier Spy, The Tourist, The Parallax View, The Tailor of Panama, Taken, Unknown, The Recruit, The Debt, The Good Shepherd and Three Days of the Condor.
Supernatural thriller: In which the film brings in an otherworldly element (such as fantasy and/or the supernatural) mixed with tension, suspense and plot twists. Sometimes the protagonist and/or villain has some psychic ability and superpowers. Examples include, Lady in the Water, Fallen, Frequency, Next, Knowing, In Dreams, Flatliners, Jacob's Ladder, Chronicle, The Skeleton Key, What Lies Beneath, Unbreakable, The Gift, and The Dead Zone.
Techno thriller: A suspense film in which the manipulation of sophisticated technology plays a prominent part. There is a bit of action and science fiction. Examples include The Thirteenth Floor, Jurassic Park, I, Robot, Eagle Eye, Hackers, The Net, Futureworld, eXistenZ and Virtuosity.
Legal thriller: A suspense film in which in which the major characters are lawyers and their employees. The system of justice itself is always a major part of these works, at times almost functioning as one of the characters. Examples include, The Pelican Brief, Presumed Innocent, The Jury, The Kappa File, The Lincoln Lawyer, Hostile Witness and Silent Witness.
