The interactive movie genre came about with the invention of laserdiscs. An interactive movie contains pre-filmed full-motion cartoons or live-action sequences, where the player controls some of the moves of the main character.
For example, when in danger, the player decides which move, action, or combination to choose. In these games, the only activity the player has is to choose or guess the move the designers intend him to make.
Interactive movies usually differ from games that simply use full-motion video, FMV, extensively between scenes in that they try to integrate it into the gameplay itself. This has been used in everything from racing games to fighting games. A few adventure games have tried to use the term to liken the storytelling of their games to those in movies, most notably the later Tex Murphy games and the more recent Fahrenheit (Indigo Prophecy), although they are more aptly classified as genre hybrids. Elements of interactive movies have been adapted for game cut scenes, in the form of Quick Time Events, to keep the player alert. Games like Resident Evil 4 present obvious in-game prompts for the player to react to. Not doing so usually results in the player character either getting hurt or outright killed.
