http://en.wikipedia.org/wiki/Continuity_editing

Continuity editing is the predominant style of editing in narrative cinema and television. The purpose of continuity editing is to smooth over the inherent discontinuity of the editing process and to establish a logical coherence between shots.

In most films, logical coherence is achieved by cutting to continuity, which emphasizes smooth transition of time and space. However, some films incorporate cutting to continuity into a more complex classical cutting technique, one which also tries to show psychological continuity of shots. The montage technique relies on symbolic association of ideas between shots rather than association of simple physical action for its continuity. 

http://en.wikipedia.org/wiki/180_degree_rule

The 180° rule is a basic guideline in film making that states that two characters (or other elements) in the same scene should always have the same left/right relationship to each other. If the camera passes over the imaginary axis connecting the two subjects, it is called crossing the line. The new shot, from the opposite side, is known as a reverse angle.

http://en.wikipedia.org/wiki/Cutting_on_action

Cutting on action or matching on action refers to a film editing technique where the editor cuts from one shot to another view that matches the first shot's action. Although the two shots may have actually been shot hours apart from each other, cutting on action gives the impression of continuous time when watching the edited film. By having a subject begin an action in one shot and carry it through to completion in the next, the editor creates a visual bridge which distracts the viewer from noticing the cut or noticing any slight continuity error between the two shots.

http://en.wikipedia.org/wiki/Shot_reverse_shot

Shot reverse shot (or shot/countershot) is a film technique where one character is shown looking at another character (often off-screen), and then the other character is shown looking back at the first character. Since the characters are shown facing in opposite directions, the viewer assumes that they are looking at each other.

http://en.wikipedia.org/wiki/Thriller_(genre)


Thriller is a genre of literature, film, and television that uses suspense, tension, and excitement as the main elements. The primary subgenres are mystery, crime, and psychological thrillers. After the assassination of President Kennedy, political thriller and paranoid thriller films became very popular. The brightest examples of thrillers are the Hitchcock’s movies.The cover-up of important information from the viewer and fight/chase scenes are common methods in all of the thriller subgenres, although each subgenre has its own characteristics and methods. Common methods in crime thrillers are mainly ransoms, captivities, heists, revenge, kidnappings. More common in mystery thrillers are investigations and the whodunit technique. Common elements in psychological thrillers are mind games, psychological themes, stalking, confinement/deathtraps, horror-of-personality, and obsession. Elements such as conspiracy theories, false accusations,paranoia, and sometimes action are common in paranoid thrillers.

Characteristics

A genuine, standalone thriller is a film that provide thrills and keeps the audience cliff-hanging at the "edge of their seats" as the plot builds towards a climax. The tension usually arises when the character(s) is placed in a menacing situation, a mystery, or a trap from which escaping seems impossible. Life is threatened, usually because the principal character is unsuspectingly or unknowingly involved in a dangerous or potentially deadly situation.^[6]

Thrillers mostly take place in ordinary suburbs/cities. Though sometimes, they may take place wholly or partly in exotic settings such as foreign cities, deserts, polar regions, or the high seas. The heroes in most thrillers are frequently ordinary citizens unaccustomed to danger. However, more common in crime thrillers, they may also be "hard men" accustomed to danger, like police officers and detectives. While such heroes have traditionally been men, women lead characters have become increasingly common.

Thrillers often overlap with mystery stories but are distinguished by the structure of their plots. In a thriller, the hero must thwart the plans of an enemy rather than uncover a crime that has already happened. While a murder mystery would be spoiled by a premature disclosure of the murderer's identity, in a thriller the identity of a murderer or other villain is typically known all along. Thrillers also occur on a much grander scale: the crimes that must be prevented are serial or mass murder, terrorism, assassination, or the overthrow of governments. Jeopardy and violent confrontations are standard plot elements. While a mystery climaxes when the mystery is solved, a thriller climaxes when the hero finally defeats the villain, saving his own life and often the lives of others. In thrillers influenced by film noir and tragedy, the compromised hero is often killed in the process.

In recent years, thrillers have been slightly influenced by the horror genre; they have more gore/sadistic violence, brutality, terror, and body counts.^[7] Recent thrillers which took this route include Eden Lake, The Last House on the Left, P2, Untraceable and Funny Games

Similar distinctions separate the thriller from other overlapping genres: adventure, spy, legal, war, maritime fiction, and so on. Thrillers are defined not by their subject matter but by their approach to it. Many thrillers involve spies and espionage, but not all spy stories are thrillers. The spy novels of John le Carré, for example, explicitly and intentionally reject the conventions of the thriller. Conversely, many thrillers cross over to genres that traditionally have had few or no thriller elements. Alistair MacLean, Hammond Innes, and Brian Callison are best known for their thrillers but are also accomplished writers of man-against-nature sea stories.
